TypeScript introduced a new flag called `noImplicitOverride` as part
of TypeScript v4.3. This flag introduces a new keyword called `override`
that can be applied to members which override declarations from a base
class. This helps with code health as TS will report an error if e.g.
the base class changes the method name but the override would still
have the old method name. Similarly, if the base class removes the method
completely, TS would complain that the memeber with `override` no longer
overrides any method.
A similar concept applies to abstract methods, with the exception that
TypeScript's builtin `noImplicitOverride` option does not flag members
which are implemented as part of an abstract class. We want to enforce
this as a best-practice in the repository as adding `override` to such
implemented members will cause TS to complain if an abstract member is
removed, but still implemented by derived classes.

Currently unless a listener inside of an embedded view tries to reference something from the parent view, or if the reference is a local ref, we don't generate the view restoration instructions and we allow for the value to be picked up from the context object in the function parameters. The problem is that the listener is only run during creation mode and the context object may have been swapped out afterwards.
These changes fix the issue by always generating the view restoration instructions for listeners inside templates.
Fixes#42698.

In #42492 the template type checker became capable of replicating a
wider range of generic type parameters for use in template type-check
files. Any literal types within a type parameter would however emit
invalid code, as TypeScript was emitting the literals using the text as
extracted from the template type-check file instead of the original
source file where the type node was taken from.
This commit works around the issue by cloning any literal types and
marking them as synthetic, signalling to TypeScript that the literal
text has to be extracted from the node itself instead from the source
file.
This commit also excludes `import()` type nodes from being supported,
as their module specifier may potentially need to be rewritten.

We accidentally started shipping `.mjs` files for the following
modules (or module paths) as of the v12.1.0-next.2 tag:
- `@angular/compiler-cli`
- `@angular/common/locales`
- `@angular/bazel`
- `@angular/benchpress`
- `@angular/core/schematics`
- `@angular/elements/schematics`
- `@angular/language-service`
- `@angular/localize/schematics`,
- `@angular/localize/tools`
- `zone.js`
This did not cause any issues for consumers but we
want to not ship these files without having them wired
up in `package.json` files. We accidentally started shipping
these `.mjs` files due to a NodeJS update which wired up the
other JavaScript module output flavors in the `pkg_npm` rule.

Introduces a rule that collects declared JavaScript module output files
from a list of dependencies based on a configurable JavaScript module
provider. The extracted outputs are exposed within the `DefaultInfo` provider.
Targets defined using this rule can be used as input for rules that
require JavaScript sources, or if there are multiple JavaScript output
variants defined for a target while for example only the `JSModuleInfo`
outputs are of interest.
As an example: This rule is helpful in combination with `ts_library` and
`ng_module` as those rule expose multiple output flavors (which are
distinguishable by the JavaScript module providers as imported from `providers.bzl`).
i.e. these rules expose flavors for named AMD modules and ECMAScript module output.
If we want to ship a NPM package only using ECMAScript modules for
example, we could extract all `JSEcmaScriptModuleInfo`-denoted output
and feed that into the `pkg_npm` rule, compared to bringing in all
output flavors.

Updates the Bazel NodeJS rules to v4.0.0-beta.0. This is necessary
so that the Angular components repo can update, and it's generally
good to stay as up-to-date as possible with the Bazel rules as it's
easy to fall behind, and updating early allows us to discover issues
affecting our tooling earlier (where they are easier to address due to
e.g. potential breaking change policy).
PR Close#42760
This commit applies changes to `@angular/bazel` which are necessary
to support the Bazel NodeJS rules v4.0.0. The Bazel NodeJS rules
no longer support the `_tslibrary` option for the `LinkablePackageInfo`
provider and therefore we need to stop using it. Due to this removal,
we also need to add two new attributes called `package_name` and
`package_path` so that the API of `ng_module` matches `ts_library`.
Note: This is denoted as `refactor` as we currently are not able to
merge feature commits into patch branches, but we want the tooling
to not diverge significantly between the patch and next branch. It is
planned to update the merge tooling to allow for such changes to land.

Skydoc is no longer used as `@angular/bazel` is no longer a
public API. The Sass rules were only used in a single place
in the repo where Sass is not really needed and has just been
added by accident most likely. We want to remove the Sass dependency
in preparation for Rules NodeJS v4.x where the Sass rules currently
still use an older version of `@bazel/worker` that is incompatible.

We removed `bazel-toolchains` from the repository since dev-infra
provides the RBE platforms now (in a way where they are not reliant
on the Bazel version), so the comment in `.bazelversion` can be
removed.

Rollup just prints a warning if an import cannot be resolved and ends up
being treated as an external dependency. This in combination with the
`silent = True` attribute for `rollup_bundle` means that bundles might
end up being extremely small without people noticing that it misses
actual imports.
To improve this situation, the warning is replaced by an error if
an import cannot be resolved.
This unveiles an issue with the `ng_rollup_bundle` macro from
dev-infra where imports in View Engine were not resolved but ended
up being treated as external. This did not prevent benchmarks using
this macro from working because the ConcatJS devserver had builtin
resolution for workspace manifest paths. Though given the new check
for no unresolved imports, this will now cause errors within Rollup, and
we need to fix the resolution. We can fix the issue by temporarily
enabling workspace linking. This does not have any performance
downsides.
To enable workspace linking (which we might need more often in the
future given the linker taking over patched module resolution), we
had to rename the `angular` dependency to a more specific one so
that the Angular linker could link into `node_modules/angular`.

When another navigation is triggered during an in-process navigation and
the `canceledNavigationResolution` is `'computed'`, we should not
attempt to restore the browser history using `history.go`. Doing that
would trigger a third navigation through the router which would conflict
with the new navigation that we were trying to process. Instead, we
treat this as a redirect and skip the history restoration attempt. This
acts similarly to returning `UrlTree` from a guard.

Previously, the ServiceWorker assumed that a client found in
`clientVersionMap` would exist (i.e. it could be retrieved via
`clients.get()`). However, if a browser tab had been closed, the
corresponding client (while present in `clientVersionMap`, which is only
updated on ServiceWorker initialization) would not be retrievable via
`clients.get()`.
This commit fixes it by checking whether the client exists before trying
to notify it about an unrecoverable state.
