This commit removes `@angular-devkit/build-angular` from package.json
for a project that opts into Bazel. This is because the package adds a
dependency on node-sass, which is rejected by Bazel due to its absense.
This commit also appends to `scripts.postinstall` if it already exists.
This is needed because `ng new` in CLI v9 now automatically adds a
postinstall step for `ngcc`.

Turns out that writing to global state is more expensive than writing to
a property on an object.
Slower:
````
let count = 0;
function increment() {
count++;
}
```
Faster:
````
const state = {
count: 0
};
function increment() {
state.count++;
}
```
This change moves all of the instruction state into a single state object.

This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.
1. Move the global side-effect import from the primary entry-point to a
secondary entry-point @angular/localize/init.
This has two benefits: first it allows the top level entry-point to
contain tree-shakable shareable code; second it gives the side-effect
import more of an "action" oriented name, which indicates that importing
it does something tangible
2. Move all the source code into the top src folder, and import the localize
related functions into the localize/init/index.ts entry-point.
This allows the different parts of the package to share code without
a proliferation of secondary entry-points (i.e. localize/utils).
3. Avoid publicly exporting any utilities at this time - the only public
API at this point are the global `$localize` function and the two runtime
helpers `loadTranslations()` and `clearTranslations()`.
This does not mean that we will not expose additional helpers for 3rd
party tooling in the future, but it avoid us preemptively exposing
something that we might want to change in the near future.
Notes:
It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.
Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.
The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.
BREAKING CHANGES:
The entry-points have changed:
* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.
* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.

`ngcc` supports both synchronous and asynchronous execution. The default
mode when using `ngcc` programmatically (which is how `@angular/cli` is
using it) is synchronous. When running `ngcc` from the command line
(i.e. via the `ivy-ngcc` script), it runs in async mode.
Previously, the work would be executed in the same way in both modes.
This commit improves the performance of `ngcc` in async mode by
processing tasks in parallel on multiple processes. It uses the Node.js
built-in [`cluster` module](https://nodejs.org/api/cluster.html) to
launch a cluster of Node.js processes and take advantage of multi-core
systems.
Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when
processing the angular.io app (apparently depending on the OS, number of
available cores, system load, etc.). Further investigation is needed to
better understand these numbers and identify potential areas of
improvement.

This is a prerequisite to fix a bug in template completions whereby
completion of the string `ti` for the variable `title` results in

This is because the position where the completion is requested is used

`replacementSpan` should be used to indicate the span of text that needs
to be replaced. Angular's own `Completion` interface is insufficient to
hold this information. Instead, we should just use ts.CompletionEntry.

This test uses localization in the `AppComponent` component:

PR Close#31609
This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.
BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.
```ts
import '@angular/localize';
```
For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.

can probably go in and make this nicer in a future PR, though I'm not
sure what the best architecture should be yet.

Reworks the compiler to output the factories for directives, components and pipes under a new static field called `ngFactoryFn`, instead of the usual `factory` property in their respective defs. This should eventually allow us to inject any kind of decorated class (e.g. a pipe).
**Note:** these changes are the first part of the refactor and they don't include injectables. I decided to leave injectables for a follow-up PR, because there's some more cases we need to handle when it comes to their factories.

Angular hooks come after 2 flavours:
- init hooks (OnInit, AfterContentInit, AfterViewInit);
- check hooks (OnChanges, DoChanges, AfterContentChecked, AfterViewChecked).
We need to do more processing for init hooks to ensure that those hooks
are run once and only once for a given directive (even in case of errors).
As soon as all init hooks execute to completion we are only left with the
checks to execute.
It turns out that keeping track of the remaining init hooks to execute is
rather expensive (multiple LView flags reads, writes and checks). But we can
observe that non of this tracking is needed as soon as all init hooks are
completed.
This PR takes advantage of the above observations and splits hooks processing
functions into:
- init-specific (slower but less common);
- check-specific (faster and more common).
NOTE: there is code duplication in this PR and it is left like this intentinally:
hand-inlining this perf-critical code makes the view refresh process substentially
faster.

This does not affect the way Bazel builds in the Angular repo work, since

Additionally, projects using @angular/bazel still use View Engine builds

Since most of the Angular repo tests are still written against View Engine
(particularly because we still publish VE packages to NPM), this switch
also requires lots of `enableIvy: false` flags in tsconfigs throughout the

In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.
In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.
This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.
3) It aligns the semantics of Ivy `Sanitizer` with that of the Ivy sanitization rules.
4) It refactors `DomSanitizer` to use same functions as Ivy sanitization for consistency.

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.
