This change aligns with the supported Node.js versions of the Angular CLI.
See: https://github.com/angular/angular-cli/pull/24026
BREAKING CHANGE: Angular no longer supports Node.js versions `14.[15-19].x` and `16.[10-12].x`. Current supported versions of Node.js are `14.20.x`, `16.13.x` and `18.10.x`.

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).

This commit updates the `node` engines range for all Angular
framework packages to:
* No longer support NodeJS v12 `< 12.20`. This is done because APF v13
uses package export patterns which are only supported as of v12.20.
https://nodejs.org/api/packages.html#packages_subpath_patterns.
* Allows for the latest v16 NodeJS versions. This matches with the CLI
which added NodeJS v16 support with https://github.com/angular/angular-cli/pull/21854.
We already limit this to `>= v16.10.0` in preparation to only
supporting the LTS minors of Node v16.
BREAKING CHANGE: NodeJS versions older than `v12.20.0` are no longer
supported due to the Angular packages using the NodeJS package exports
feature with subpath patterns.
PR Close#43740
With the changes to support APF v13 in the `ng_package` rule, we have
removed the ambiguous `entry_point` attribute. The attribute suggested
that it would be used for determining the primary entry-point input
file. This was not the case as the flat module output file is consulted
for bundling et at. The attribute has been renamed to match its
purposed (renamed to `primary_bundle_name`).
We no longer need to set that attribute because the primary bundle
name is (1) not of relevance for consumers and (2) the rule already
infers the bundle name properly from the Bazel package.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

We can't update the framework to rxjs7 until version 13, because it contains breaking changes, but we can allow users to opt into it since all of our code should be compatible.
These changes expand the allowed version range of rxjs and add an integration test to verify that we don't get compilation errors. Note that we also have a test that runs the AIO examples against rxjs 7 already (#42660).

Some `elements` tests rely on `window.customElements` being available.
On browsers where this was not present, the tests were skipped.
This commit includes the `@webcomponents/custom-elements` polyfill in
order to be able to run all `elements` tests on older browsers, which do
not natively support Custom Elements.
This, also, fixes the [saucelabs_ivy][1] and [saucelabs_view_engine][2]
CI jobs (part of the `monitoring` workflow), which have been failing
recently on IE 11 (probably due to the update to TS 4.2.3).

As with regular Angular components, Angular elements are expected to
have their views update when inputs change.
Previously, Angular Elements views were not updated if the underlying
component used the `OnPush` change detection strategy.
This commit fixes this by calling `markForCheck()` on the component
view's `ChangeDetectorRef`.
NOTE:
This is similar to how `@angular/upgrade` does it:
3236ae0ee1/packages/upgrade/src/common/src/downgrade_component_adapter.ts (L146).

`ComponentNgElementStrategy` is supposed to call `ngOnChanges()` on the
underlying component instance if available, but not fail if the
component does not have an `ngOnChanges()` method. This works as
expected. However, the test used to verify that was invalid; i.e. the
test would pass even if `ComponentNgElementStrategy` would try to call
`ngOnChanges()` on a component without such a method.
This commit replaces the invalid test with a new one that correctly
verifies that `ComponentNgElementStrategy` does not try to call
`ngOnChanges()`.

Previously, the `componentRef` property of `FakeComponentFactory` used
in `elements` tests was initialy set to a spy object with all mock
properties defined as spied methods. Later, the properties where
overwritten to the actual mock values.
This commit simplifies the creation of `componentRef` by correctly using
the arguments of [jasmine.createSpyObj()][1] to specify the desired
shape of the spy object (separating spied properties from methods and
directly providing the mock values).

Support for IE<11 is being removed in v11. PR #39090 removed some code

Now that there are no longer multiple code-paths (which was previously

example, to avoid unnecessary functions calls and to avoid iterating
over a component's inputs multiple times).

Default change detection fails in some cases for @angular/elements where

Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that `NgElementImpl` [subscribed to events][1] _after_
calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Changing `NgElementImpl` to subscribe to `NgElementStrategy#events`
(if available) before calling `NgElementStrategy#connect()` (which
initializes the component instance) if available.
3. Falling back to the old behavior (subscribing to `events` after
calling `connect()` for strategies that do not initialize `events`
before their `connect()` is run).
NOTE:
By falling back to the old behavior when `NgElementStrategy#events` is
not initialized before calling `NgElementStrategy#connect()`, we avoid
breaking existing custom `NgElementStrategy` implementations (with
@remackgeek's [ElementZoneStrategy][4] being a commonly used example).

In the current version of zone.js, zone.js uses it's own package format, and it is not following the rule
of Angualr package format(APF), so it is not easily to be consumed by Angular CLI or other bundle tools.
For example, zone.js npm package has two bundles,
1. zone.js/dist/zone.js, this is a `es5` bundle.
2. zone.js/dist/zone-evergreen.js, this is a `es2015` bundle.
And Angular CLI has to add some hard-coding code to handle this case, o5376a8b139/packages/schematics/angular/application/files/src/polyfills.ts.template (L55-L58)
This PR upgrade zone.js npm package format to follow APF rule, https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs/edit#heading=h.k0mh3o8u5hx
The updated points are:
1. in package.json, update all bundle related properties
```
"main": "./bundles/zone.umd.js",
"module": "./fesm2015/zone.js",
"es2015": "./fesm2015/zone.js",
"fesm2015": "./fesm2015/zone.js",
```
2. re-organize dist folder, for example for `zone.js` bundle, now we have
```
dist/
bundles/
zone.js // this is the es5 bundle
fesm2015/
zone.js // this is the es2015 bundle (in the old version is `zone-evergreen.js`)
```
3. have several sub-packages.
1. `zone-testing`, provide zone-testing bundles include zone.js and testing libraries
2. `zone-node`, provide zone.js implemention for NodeJS
3. `zone-mix`, provide zone.js patches for both Browser and NodeJS
All those sub-packages will have their own `package.json` and the bundle will reference `bundles(es5)` and `fesm2015(es2015)`.
4. keep backward compatibility, still keep the `zone.js/dist` folder, and all bundles will be redirected to `zone.js/bundles` or `zone.js/fesm2015` folders.
