TypeScript supports ECMAScript private identifiers. It can happen that
developers intend to access such members from within an expression.
This currently results in an unclear error from the lexer. e.g.
```
'Parser Error: Unexpected token # at column 1 in [{{#myField}}] in C:/test.ts@5:2
```
We could improve such errors by tokenizing private identifiers similar to
how the TypeScript scanner processes them. Later we can report better
errors in the expression parser or in the typecheck block. This commit
causes all private identifier tokens to be disallowed, so it never
reaches the type checker. This is done intentionally as private
identifiers should not be considered valid Angular syntax, especially
because private fields are not guaranteed to be accessible from within
a component/directive definition (e.g. there cases where a template
function is generated outside of the class; which results in private
members not being accessible; and this results in mixed/confusing
behavior).

Currently the ng-dev release tool always run `bazel clean` before
calling the configured build release function. The clean is necessary
to ensure the release output is actually built; and not restored
from previous builds which could have different bazel workspace
status variables (which provide the NPM package version).
Instead of doing this as part of the release tool, the
actual script running to build the release output should
run the `bazel clean`. The release tool does not intend to
know about details on how the release output is built. This
is necessary because the build setup could vary between version
branches (especially for older ones; such as LTS version branches).

We skip event listeners on non-element host nodes (e.g. `ng-container` or `ng-element`), because they don't map to a DOM node so there's nothing to bind the event to. The problem is that this also prevents listeners bound to global targets from being bound.
These changes add an extra condition to allow for the event to be bound if it has a custom event target resolver.
Fixes#14191.

* recently, performance events started showing up with a -bpstart and -bpend
suffix to indicate their being the start and end events for our performance
testing. to fix this, we added an additional check for those suffixes in
addition to the old checks.

The Validator and AsyncValidator interfaces provide a callback, `registerOnValidatorChange(fn)`. `registerOnValidatorChange` is supposed to be fired at least once to register `fn` with the validator. `fn` is then called by the validator whenever its inputs change. This was previously not happening for FormGroup validators, and is now fixed.

Previously, the `updating-to-version-*` URLs would redirect to the next
version update guide. More specifically:
- `/guide/updating-to-version-10` --> `https://v11.angular.io/guide/updating-to-version-11`
- `/guide/updating-to-version-11` --> `/guide/updating-to-version-12`
This seems confusing and inconsistent. Either all URLs should redirect
to the latest update guide (currently `/guide/updating-to-version-12`)
or each URL should redirect to the corresponding version.
This commit implements the second approach:
- `/guide/updating-to-version-10` --> `https://v10.angular.io/guide/updating-to-version-10`
- `/guide/updating-to-version-11` --> `https://v11.angular.io/guide/updating-to-version-11`

Prior to this change, any inserted `<style>` nodes into shadow dom trees would be retained
in memory, even after the shadow dom tree has been removed. This commit fixes the memory
leak by tracking the inserted `<style>` nodes per host element, such that removal of the
host element also releases the style nodes.

It is important to use the correct major version of the Angular CLI when
following the examples in the tutorials. This commit provides a custom
element that renders an appropriate dist-tag in the setup step of
the tutorial when the docs are not in "stable" mode.

When aio yarn docs-only command runs on v12.14.1 it fails details given on issue #41979. Upgrading node version to v12.17.0 solves this but creates a new warning (node:467072) ExperimentalWarning: The ESM module loader is experimental.
This warning gets removed in v12.20.0. Upgrading node version to 12.20.0

The JIT compiler has a mapping from component to the owning NgModule
and tracks whether a certain NgModule class has been verified; these
maps causes any JIT compiled component and NgModule to be retained even
if they are no longer referenced from anywhere else. This commit
switches the maps to `WeakMap` to allow garbage collecting any
components and NgModules that are no longer referenced elsewhere.

Now that there is no need to work around the source-map bug in TypeScript
(https://github.com/Microsoft/TypeScript/issues/29300) we can just use
`resolvedTemplateUrl` for the source-map URL, rather than having a separate
property.
