c46d533b22 build: switch devmode output to es2015 (#44505)
To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.

Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:

ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

c8cd5d5f2c build: switch all instances from ng_rollup_bundle to app_bundle (#44490)
The `ng_rollup_bundle` rule has been replaced with a new rule called
`app_bundle`. This rule replicates the Angular v13 optimization
pipeline in the CLI, so that we can get better benchmarking results.
Also the rule is much simpler to maintain as it relies on ESbuild.

The old `ng_rollup_bundle` rule did rely on e.g. build-optimizer that no
longer has an effect on v13 Angular packages, so technically size
tests/symbol tests were no longer as correct as they were before. This
commit fixes that.

A couple of different changes and their explanation:

* Language-service will no longer use the benchmark rule for creating
  its NPM bundles! It will use plain `rollup_bundle`. ESBuild would have
  been nice but the language-service relies on AMD that ESBuild cannot
  generate (yet?)

* Service-worker ngsw-worker.js file was generated using the benchmark
  bundle rule. This is wrong. We will use a simple ESbuild rule in the
  future. The output is more predictable that way, and we can have a
  clear use of the benchmark bundle rule..

* A couple of benchmarks in `modules/` had to be updated to use e.g.
  `initTableUtils` calls. This is done because with the new rule, all
  files except for the entry-point are considered side-effect free. The
  utilities for benchmarks relied on side-effects in some
  transitively-loaded file (bad practice anyway IMO). We are now
  initializing the utilities using a proper init function that is
  exported...

43dfab447d fix(core): destroy hooks not set up for useClass provider using forwardRef (#44281)
Fixes an issue where destroy hooks are not set up for `useClass` providers
that rely on `forwardRef` for passing the actual class reference.

Currently the destroy hooks are not captured because forward refs are
not resolved for class providers. In ES2015+ this issue becomes even
more critical if arrow-functions are used for

e.g. `useClass: () => forwardRef(..)`.

This is because arrow functions do not have a prototype, unlike in ES5
where the function assigned to `useClass` would always have a prototype.
In ES2015+ a runtime exception as followed is returned (and doesn't give
any useful indication of the forwardRef issue):

b23ce150d0 build: bundle spec files for saucelabs legacy job (#44281)
Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.

Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.

Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!

393efa54e6 fix(compiler): ensure that partially compiled queries can handle forward references (#44113)
When a partially compiled component or directive is "linked" in JIT mode, the body
of its declaration is evaluated by the JavaScript runtime. If a class is referenced
in a query (e.g. `ViewQuery` or `ContentQuery`) but its definition is later in the
file, then the reference must be wrapped in a `forwardRef()` call.

Previously, query predicates were not wrapped correctly in partial declarations
causing the code to crash at runtime. In AOT mode, this code is never evaluated
but instead transformed as part of the build, so this bug did not become apparent
until Angular Material started running JIT mode tests on its distributable output.

This change fixes this problem by noting when queries are wrapped in `forwardRef()`
calls and ensuring that this gets passed through to partial compilation declarations
and then suitably stripped during linking.

18b33e79d3 perf(core): avoid storing LView in __ngContext__ (#41358)
Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving
the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to
the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has
references to all of the child nodes of the view, as well as other internal data structures.

Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed
(see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can
slow down destruction due to a megamorphic write.

These changes aim to address the issue while reducing the performance impact by assigning a unique
ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in
a map where their unique ID is used as the key. We don't need to worry about leaks within that map,
because `LView`s are an internal data structure and we have complete control over when they are
created and destroyed.

520ff69854 perf(core): add private hooks around user code executed by the runtime (#41255)
Introduces an **internal**, **experimental** `profiler` function, which
the runtime invokes around user code, including before and after:
- Running the template function of a component
- Executing a lifecycle hook
- Evaluating an output handler

The `profiler` function invokes a callback set with the global
`ng.ɵsetProfiler`. This API is **private** and **experimental** and
could be removed or changed at any time.

This implementation is cheap and available in production. It's cheap
because the `profiler` function is simple, which allows the JiT compiler
to inline it in the callsites. It also doesn't add up much to the
production bundle.

To listen for profiler events:

```ts
ng.ɵsetProfiler((event, ...args) => {
  // monitor user code execution

ed77bfea26 test(core): fix JIT factory declaration test for IE11 (#41416)
This commit removes a check for the name of the generated factory
function, which is unimportant to test the behaviour of the code.

The name of these functions is generated from the name of the class
being instantiated. In IE11, there is no `function.name` property available
and so there is a shim for it in `third_party/shims_for_IE.js`, which patches
the `Function.property.name` property.

For performance reasons this shim writes the result of the computation
to the prototype of the function. Unfortunately, this means that any class
that extends the patched class will have the same value for `name`.

2ebe2bcb2f refactor(compiler): move factory out of injector definition (#41022)
Previously, injector definitions contained a `factory` property that
was used to create a new instance of the associated NgModule class.

Now this factory has been moved to its own `ɵfac` static property on the
NgModule class itself. This is inline with how directives, components and
pipes are created.

There is a small size increase to bundle sizes for each NgModule class,
because the `ɵfac` takes up a bit more space:

Before:

```js
let a = (() => {
  class n {}
  return n.\u0275mod = c.Cb({type: n}),
  n.\u0275inj = c.Bb({factory: function(t) { return new (t || n) }, imports: [[e.a.forChild(s)], e.a]}),
  n
})(),
```

After:

```js
let a = (() => {
  class n {}
  return n.\u0275fac = function(t) { return new (t || n) },
  n.\u0275mod = c.Cb({type: n}),
  n.\u0275inj = c.Bb({imports: [[r.a.forChild(s)], r.a]}),
  n
})(),
```

In other words `n.\u0275fac = ` is longer than `factory: ` (by 5 characters)
and only because the tooling insists on encoding `ɵ` as `\u0275`.

This can be mitigated in a future PR by only generating the `ɵfac` property
if it is actually needed.

d516113803 refactor(core): Remove the need for explicit static query instruction (#40091)
Because the query now has `flags` which specify the mode, the static query
instruction can now be remove. It is simply normal query with `static` flag.

e32b6256ce fix(core): QueryList should not fire changes if the underlying list did not change. (#40091)
Previous implementation would fire changes `QueryList.changes.subscribe`
whenever the `QueryList` was recomputed. This resulted in artificially
high number of change notifications, as it is possible that recomputing
`QueryList` results in the same list. When the `QueryList` gets recomputed
is an implementation detail and it should not be the thing which determines
how often change event should fire.

This change introduces a new `emitDistinctChangesOnly` option for
`ContentChildren` and `ViewChildren`.

```
export class QueryCompWithStrictChangeEmitParent {
  @ContentChildren('foo', {
    // This option will become the default in the future
    emitDistinctChangesOnly: true,
  })
  foos!: QueryList<any>;
}

b48eabddb8 refactor(compiler-cli): include template source directly inside declaration object (#40383)
The `template` and `isInline` fields were previously stored in a nested
object, which was initially done to accommodate for additional template
information to support accurate source maps for external templates. In
the meantime the source mapping has been accomplished in a different
way, and I feel this flattened structure is simpler and smaller so is
preferable over the nested object. This change also makes the `isInline`
property optional with a default value of `false`.

da6c739bb6 test(core): update test expectation to account for IE11 anonymous function name (#40342)
The "monitoring" workflow has been failing since #40127 was merged,
due to a Saucelabs test failure in Internet Explorer 11. The issue is
with the test's expectation which does not account for Ivy instruction
invocations to use "anonymous" instead of the instruction's function
name. This commit changes the test expectation to also accept
"anonymous", which was already the case for similar expectations.

d4327d51d1 feat(compiler-cli): JIT compilation of component declarations (#40127)
The `ɵɵngDeclareComponent` calls are designed to be translated to fully
AOT compiled code during a build transform, but in cases this is not
done it is still possible to compile the declaration object in the
browser using the JIT compiler. This commit adds a runtime
implementation of `ɵɵngDeclareComponent` which invokes the JIT compiler
using the declaration object, such that a compiled component definition
is made available to the Ivy runtime.

The `render3` test targets are currently also executed for ViewEngine
builds, even though the `render3` infrastructure only concerns Ivy
infrastructure. This commit tags the test targets as ivy-only to disable
those tests for View Engine.
