Interestingly enough, our rollup bundle optimization pipeline
did not work properly before 1b827b058e5060963590628d4735e6ac83c6dfdd.
Unused declarations were not elided because build optimizer did not
consider the Angular packages as side-effect free. Build optimizer has
a hard-coded list of Angular packages that are considered side-effect
free. Though this one did not match in the old version of the rollup
bundle rule, as internal sources were resolved through their resolved
bazel-out paths. Hence build optimizer could not detect the known
Angular framework packages. Now though, since we leverage the
Bazel-idiomatic `@bazel/rollup` implementation, sources are resolved
through linked `node_modules`, and build optimizer is able to properly
detect files as side-effect free.

The language-service package currently sets the `module` `package.json`
property and refers to a folder called `fesm5`. The language-service
though does not build with `ng_package` so this folder never existed.
Now with APF v10, ng package would not generate this folder either.
We should just remove the property as the primary entry-point is
the UMD bundle resolved through `main`. There is no module flavour
exposed to the NPM package as `pkg_npm` uses the named AMD module
devmode output that doesn't work for `module`.

Refactors the `ng_rollup_bundle` rule to a macro that relies on
the `@bazel/rollup` package. This means that the rule no longer
deals with custom ESM5 flavour output, but rather only builds
prodmode ES2015 output. This matches the common build output
in Angular projects, and optimizations done in CLI where
ES2015 is the default optimization input.
The motiviation for this change is:
* Not duplicating rollup Bazel rules. Instead leveraging the official
rollup rule.
* Not dealing with a third TS output flavor in Bazel.The ESM5 flavour has the
potential of slowing down local development (as it requires compilation replaying)
* Updating the rule to be aligned with current CLI optimizations.
This also _fixes_ a bug that surfaced in the old rollup bundle rule.
Code that is unused, is not removed properly. The new rule fixes this by
setting the `toplevel` flag. This instructs terser to remove unused
definitions at top-level. This matches the optimization applied in CLI
projects. Notably the CLI doesn't need this flag, as code is always
wrapped by Webpack. Hence, the unused code eliding runs by default.

As of Angular Package Format v10, we no longer ship a `fesm5` and
`fesm5` output in packages. We made this change to the `ng_package`
rule but intentionally did not clean up related build actions.
This follow-up commit cleans this up by:
* No longer building fesm5 bundles, or providing esm2015 output.
* No longer requesting and building a third flavor for ESM5. We can
use TSC to downlevel ES2015 sources/prodmode output similarly to how it
is done in `ng-packagr`.
The third output flavor (ESM5) resulted in a build slow-down as we
required a full recompilation of sources. Now, we only have a single
compilation for prodmode output, and then downlevel it on-demand
to ES5 for the UMD bundles. Here is timing for building the release
packages in `angular/angular` before this change, and afterwards:
* Before: 462.157s = ~7.7min
* After: 339.703s = ~5.6min

We recently added a transformer to NGC that is responsible for downleveling Angular
decorators and constructor parameter types. The primary goal was to mitigate a
TypeScript limitation/issue that surfaces in Angular projects due to the heavy
reliance on type metadata being captured for DI. Additionally this is a pre-requisite
of making `tsickle` optional in the Angular bazel toolchain.
See: 401ef71ae5 for more context on this.
Another (less important) goal was to make sure that the CLI can re-use
this transformer for its JIT mode compilation. The CLI (as outlined in
the commit mentioned above), already has a transformer for downleveling
constructor parameters. We want to avoid this duplication and exported
the transform through the tooling-private compiler entry-point.
Early experiments in using this transformer over the current one, highlighted
that in JIT, class decorators cannot be downleveled. Angular relies on those
to be invoked immediately for JIT (so that factories etc. are generated upon loading)
The transformer we exposed, always downlevels such class decorators
though, so that would break CLI's JIT mode. We can address the CLI's
needs by adding another flag to skip class decorators. This will allow
us to continue with the goal of de-duplication.

Commit 24b2f1da2b introduced an `NgCompiler` which operates on a
`ts.Program` independently of the `NgtscProgram`. The NgCompiler got its
`IncrementalDriver` (for incremental reuse of Angular compilation results)
by looking at a monkey-patched property on the `ts.Program`.
This monkey-patching operation causes problems with the Angular indexer
(specifically, it seems to cause the indexer to retain too much of prior
programs, resulting in OOM issues). To work around this, `IncrementalDriver`
reuse is now handled by a dedicated `IncrementalBuildStrategy`. One
implementation of this interface is used by the `NgtscProgram` to perform
the old-style reuse, relying on the previous instance of `NgtscProgram`
instead of monkey-patching. Only for `NgTscPlugin` is the monkey-patching
strategy used, as the plugin sits behind an interface which only provides
access to the `ts.Program`, not a prior instance of the plugin.

This checks for a Bazel flag in `ng_module()` in the `_renderer` attribute
which specifies the renderer to use for the build.
The main advantage of this flag is that it can be overridden with [Bazel
transitions](https://docs.bazel.build/versions/master/skylark/config.html),
giving much more flexibility for migrating individual applications in a
Bazel workspace to Ivy.
This flag is not intended to replace `--config ivy` or
`--define angular_ivy_enabled=True` (although it technically could). As a
result, this flag is not and will not actually be used anywhere in the
`angular/angular` repo. Instead, a `string_flag()` is provided internally
which sets the renderer via a transition. See http://cl/315749946.
Note that this does **not** introduce a dependency on Skylib for
`angular/angular`. The dependency isn't actually necessary because
`BuildSettingInfo` is not used externally anyways. By doing this, it is not
necessary for downstream, external workspaces to depend on Skylib.

This PR changes the logic for determining when to skip route processing from
using the URL of the last attempted navigation to the actual resulting URL after
that transition.
Because guards may prevent navigation and reset the browser URL, the raw
URL of the previous transition may not match the actual URL of the
browser at the end of the navigation process. For that reason, we need to use
`urlAfterRedirects` instead.
Other notes:
These checks in scheduleNavigation were added in eb2ceff4ba
The test still passes and, more surprisingly, passes if the checks are removed
completely. There have likely been changes to the navigation handling that
handle the test in a different way. That said, it still appears to be important
to keep the checks there in some capacity because it does affect how many
navigation events occur. This addresses an issue that came up in #16710: https://github.com/angular/angular/issues/16710#issuecomment-634869739
This also partially addresses #13586 in fixing history for imperative
navigations that are cancelled by guards.

Previously, ngcc would only be able to match an ngcc configuration to
packages that were located inside the project's top-level
`node_modules/`. However, if there are multiple versions of a package in
a project (e.g. as a transitive dependency of other packages), multiple
copies of a package (at different versions) may exist in nested
`node_modules/` directories. For example, one at
`<project-root>/node_modules/some-package/` and one at
`<project-root>/node_modules/other-package/node_modules/some-package/`.
In such cases, ngcc was only able to detect the config for the first
copy but not for the second.
This commit fixes this by returning a new instance of
`ProcessedNgccPackageConfig` for each different package path (even if
they refer to the same package name). In these
`ProcessedNgccPackageConfig`, the `entryPoints` paths have been
processed to take the package path into account.

This commit adds a `packageName` property to the `EntryPoint` interface.
In a subsequent commit this will be used to retrieve the correct ngcc
configuration for each package, regardless of its path.
PR Close#37040
In order to retrieve the ngcc configuration (if any) for an entry-point,
ngcc has to detect the containing package's version.
Previously, ngcc would try to read the version from the entry-point's
`package.json` file, which was different than the package's top-level
`package.json` for secondary entry-points. For example, it would try to
read it from `node_modules/@angular/common/http/package.json` for
entry-point `@angular/common/http`. However, the `package.json` files
for secondary entry-points are not guaranteed to include a `version`
property.
This commit fixes this by first trying to read the version from the
_package's_ `package.json` (falling back to the entry-point's
`package.json`). For example, it will first try to read it from
`@angular/common/package.json` for entry-point `@angular/common/http`.

Rename the `package` property to `packagePath` on the `EntryPoint`
interface. This makes it more clear that the `packagePath` property

`packageName` property that will be added in a subsequent commit.
This commit also re-orders the `EntryPoint` properties to group related
properties together and to match the order of properties on instances
with that on the interface.
PR Close#37040
Previously, when an entry-point was ignored via an ngcc config, ngcc
would scan sub-directories for sub-entry-points, but would not use the
correct `packagePath`. For example, if `@angular/common` was ignored, it
would look at `@angular/common/http` but incorrectly use
`.../@angular/common/http` as the `packagePath` (instead of
`.../@angular/common`). As a result, it would not retrieve the correct
ngcc config for the actual package.
This commit fixes it by ensuring the correct `packagePath` is used, even
if the primary entry-point corresponding to that path is ignored. In
order to do this, a new return value for `getEntryPointInfo()` is added:
`IGNORED_ENTRY_POINT`. This is used to differentiate between directories
that correspond to no or an incompatible entry-point and those that
correspond to an entry-point that could otherwise be valid but is
explicitly ignored. Consumers of `getEntryPointInfo()` can then use this
info to discard ignored entry-points, but still use the correct
`packagePath` when scanning their sub-directories for secondary
entry-points.

In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.
Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)
Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.
PR removes the wrong work around logic. (This will improve the bundle size.)

This is a known issue of zone.js,
```
(window as any)[(Zone as any).__symbol__('setTimeout')](() => {
let log = '';
button.addEventListener('click', () => {
Zone.current.scheduleMicroTask('test', () => log += 'microtask;');
log += 'click;';
});
button.click();
expect(log).toEqual('click;microtask;');
done();
});
```
Since in this case, we use native `setTimeout` which is not a ZoneTask,
so zone.js consider the button click handler as the top Task then drain the
microTaskQueue after the click at once, which is not correct(too early).
This case was an edge case and not reported by the users, until we have the
new option ngZoneEventCoalescing, since the event coalescing will happen
in native requestAnimationFrame, so it will not be a ZoneTask, and zone.js will
consider any Task happen in the change detection stage as the top task, and if
there are any microTasks(such as Promise.then) happen in the process, it may be
drained earlier than it should be, so to prevent this situation, we need to schedule
a fake event task and run the change detection check in this fake event task,
so the Task happen in the change detection stage will not be
considered as top ZoneTask.

Currently Angular internally already handles `InjectionToken` as
predicates for queries. This commit exposes this as public API as
developers already relied on this functionality but currently use
workarounds to satisfy the type constraints (e.g. `as any`).
We intend to make this public as it's low-effort to support, and
it's a significant key part for the use of light-weight tokens as
described in the upcoming guide: https://github.com/angular/angular/pull/36144.
In concrete, applications might use injection tokens over classes
for both optional DI and queries, because otherwise such references
cause classes to be always retained. This was also an issue in View
Engine, but now with Ivy, this pattern became worse, as factories are
directly attached to retained classes (ultimately ending up in the
production bundle, while being unused).
