Since we are going to replace our `app_bundle` rule (custom ESBuild +
Terser pipeline) with the real Angular CLI where shared/lazy/common
chunks may exist, we need to update the symbol extractor to support
multiple files.
We could have just merged all symbols, but this commit tries to do
better by detecting what symbols are loaded eagerly vs. lazily. This
will be very useful for e.g. defer tests or other lazy features we are
introducing in the feature.

* Fixes that the symbol extractor approval script was broken after some recent build changes.
* Fixes the `run_all_symbol_extractor_tests` script which wasn't resolving any targets, because the rule name changed.
PR Close#61407
This commit adds a step where we build all found targets in parallel, which speeds up the process of completing symbol extractor test/update.
PR Close#60573
Switches the goldens for the symbol tests to be an array of strings, rather than an array of objects where each object only has a `name` property. This makes more compact, easier to read and easier to avoid merge conflicts.

This is basically a pre-step for combining devmode and prodmode into a
single compilation. We are already achieving this now, and can claim
with confidence that we reduced possible actions by half. This is
especially important now that prodmode is used more often, but rules
potentially still using the devmode ESM sources. We can avoid double
compilations (which existed before the whole ESM migration too!).
We will measure this more when we have more concrete documentation
of the changes & a better planning document.
Changes:
* ts_library will no longer generate devmode `d.ts`. Definitions are
generated as part of prodmode. That way only prodmode can be exposed
via providers.
* applied the same to `ng_module`.
* updates migrations to bundle because *everything* using `ts_library`
is now ESM. This is actually also useful in the future if
schematics rely on e.g. the compiler.
* updates schematics for localize to also bundle. similar reason as
above.

* The Karma Bazel Saucelabs binary needs to use `.mjs` as everything in
the repo w/Bazel is supposed to be ESM.
* The symbol extractor test is updated to no longer use CommonJS
features like `require.resolve`.
PR Close#48521
Since the Bazel setup in this repo will now always use ESM,
the tooling scripts/binaries in AIO need to be switched to ESM
too. Most of the scripts are already ESM, but a few had to be converted.
Note that the Dgeni generation does not use ESM because it's unaffected
and the Dgeni CLI is used. In the future we could also update the Dgeni
setup to ESM but there is no need currently.
PR Close#48521
We modified the macros of `nodejs_binary/test` to have a rule
in between that requests the `.mjs` output. This works fine but
breaks make variable substitution for `templated_args` because
Bazel requires referenced labels to be part of the explicit `data`.
The rule in between breaks this, so we add a new argument that
can be used for such "template"/"args" data dependencies.
This can be removed when everything is ESM and we don't need
the rule in between.

The NodeJS Bazel linker does not work well on Windows because there
is no sandboxing and linker processes from different tests will attempt
to modify the same `node_modules`, causing concurrency race conditions
and resulting in flakiness.

Updates the symbol extractor to support IIFE bundles using
arrow-functions instead of function declarations. This is in preparation
for running symbol extraction tests with the overhauled optimization
pipeline for Angular v13, relying on ESBuild internally.
Also removes rollup-specific code that does not seem to be relevant
anymore / rollup will be replaced anyway.

Setting the angular_ivy_enabled environment variable to True will default Bazel builds to use the Ivy
compiler rather than defaulting to ViewEngine.

As outlined in the previous commit which enabled the `esModuleInterop`
TypeScript compiler option, we need to update all namespace imports
for `typescript` to default imports. This is needed to allow for
TypeScript to be imported at runtime from an ES module.
Similar changes are needed for modules like `semver` where the types incorrectly
suggest named exports that will not exist at runtime when imported from ESM.
This commit refactors all imports to match with the lint rule we have
configured in the previous commit. See the previous commit for more
details on why certain imports have been changed.
A special case are the imports to `@babel/core` and `@babel/types`. For
these a special interop is needed as both default imports, or named
imports break the other module format. e.g default imports would work
well for ESM, but it breaks for CJS. For CJS, the named imports would
only work, but in ESM, only the default export exist. We work around
this for now until the devmode is using ESM as well (which would be
consistent with prodmode and gives us more valuable test results). More
details on the interop can be found in the `babel_core.ts` files (two
interops are needed for both localize/or the compiler-cli).

For APF v13, terser has been updated to v5, and the prodmode output
has changed from ES2015 to ES2020. This results in some changes in
the symbol extractor test. Here are the two causes of changes:
* As said in the previous commit, Terser drops the initializer for
variables which are set to `undefined`. We have updated the symbol
extractor to always capture such declarations w/o initializer now.
This means that a couple of declarations that a couple of new
symbols are captured now. These previously didn't have an initializer
even without Terser, and just didn't show up before.
* Terser changed its inline mechanism for functions that recursively
call themselves. Such functions are no longer inlined and therefore
show up in goldens now.
PR Close#43431
Updates the symbol extractor test to work with Terser v5 that
drops the variable declaration initializer if it is explicitly set
to `undefined`. We want to capture such identifiers in the bundles
as otherwise the majority of top-level declarations which are intially
set to `undefined` would be hidden in size goldens.

Updates to the latest version of `rules_nodejs` that supports
the most recent NodeJS lts version v14.16.1.
Additionally the latest version of `rules_nodejs` provides
[a package for runfile resolution](https://github.com/bazelbuild/rules_nodejs/pull/2568) w/ types that we can leverage.

The `yarn symbol-extractor:check` and `yarn symbol-extractor:update` commands don't seem to work currently -
the script is unable to calculate the list of relevant targets. Running the `bazel query ...` command used in the
script fails due to the missing quotes around the query argument. This commit fixes the problem by updating the
script to wrap query argument into single quotes.

We recently reworked our `ng_rollup_bundle` rule to no longer output
ESM5 and to optimize applications properly (previously applications were
not optimized properly due to incorrect build optimizer setup).
This change meant that a lot of symbols have been removed from the
golden correctly. See: fd65958b88
Unfortunately though, a few symbols have been accidentally removed
because they are now part of the bundle as ES2015 classes which the
symbol extractor does not pick up. This commit fixes the symbol
extractor to capture ES2015 classes. We also update the golden to
reflect this change.

$(location) is not recommended in the bazel docs as depending on context it will either return the value of $(execpath) or $(rootpath). rules_nodejs now supports $(rootpath) and $(execpath) in templated_args of nodejs_binary.

We need to migrate to using angular_ivy_enabled value to determine whether to use
Ivy or ViewEngine for package building scripts and for size-tracking and
symbol-extract tooling.
PR Close#33983
Component defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
`ngComponentDef` to `cmp`. This is because property names
cannot be minified by Uglify without turning on property
mangling (which most apps have turned off) and are thus
size-sensitive.
Note that the other "defs" (ngDirectiveDef, etc) will be
prefixed and shortened in follow-up PRs, in an attempt to
limit how large and conflict-y this change is.

Currently when working on Windows, it's not possible to accept a new
golden for a `symbol-extractor` Bazel test. This is because the generated
executable output from the `nodejs_binary` rule (without a macro) misses
a Windows executable wrapper that sets up the proper environment
variables for the runfiles. Causing the following failure on Windows:
```
