A lot of our tests are wrapped in `{}` which serves no purpose, aside from increasing the nesting level and, in some cases, causing confusion. The braces appear to be a leftover from a time when all tests were wrapped in a `function main() {}`. The function declaration was removed in #21053, but the braces remained, presumably because it was easier to search&replace for `function main()`, but not to remove the braces at the same time.

This change adjust the equality comparator used by NgSwitch - now it
defaults to === from previously used ==. This change is based on the
following reasoning:
- align behaviour with the built-in switch block);
- improve performance (avoid type coercion);
- enable better type-checking.
BREAKING CHANGE:
the NgSwitch directive now defaults to the === equality operator,
migrating from the previously used ==. NgSwitch expressions and / or
individual condition values need adjusting to this stricter equality
check. The added warning message should help pinpointing NgSwitch
usages where adjustements are needed.

The context of an embedded view ref at some point was switched from a
getter to an actual assignable property. This is something we reverted
with the previous commit as it introduces additional complexity for our
generated code (in terms of closures capturing the `ctx`).
This change impacted the template outlet code because we actively relied
on swapping out the full context if the user changes it. Previousl,
before we allowed to swap out the context (in v16), we mutated the
initial view context if it didn't change structurally- and in other
cases the view was re-created. We improved this performance aspect with
the changes to allow for the context to be swapped out + actually also
fixed a bug where the initial context object was mutated and the user
could observe this change.
This commit adjusts for context not being replacable- while still
keeping the bugs fixed and preserving the performance wins of not
having to destroy/re-create the view whenever the context changes.

The below error is displayed during some tests
```js
ERROR: 'Unhandled Promise rejection:', 'Cannot read properties of null (reading 'markForCheck')', '; Zone:', 'ProxyZone', '; Task:', 'Promise.then', '; Value:', TypeError: Cannot read properties of null (reading 'markForCheck')
TypeError: Cannot read properties of null (reading 'markForCheck')

```
This is caused by the fact that `ref` in `AsyncPipe` is initialized with a value of `null` which causes `_updateLatestValue` to fail since it is not expected to be `null`.
This change ensures that a `ref` is always provided and that all subscriptions are disposed off after each test.

This commit represents rewrite of the NgClass directive to address
severe performance problem (excessive DOM mutation). The modified
algorithm removes all the known performance clifs and has number of
desirable properties:
- it is shorter and (arguably) easier to follow;
- drops usage of existing differs thus limiting dependencies on other
part of the code without increasing size of the directive;
- doesn't degrade any other performance metrics.

Since we generate a `.mjs` file as entry-point for jasmine tests,
a couple of issues prevented the transitive dependencies from
bootstrap targets to be brought in (causing resolution errors):
1. The `_files` (previously `_esm2015`) targets are no longer needed,
and they also miss all the information on runfiles.
2. The aspect for computing linker mappings does not respect the
`bootstrap` attribute from the `spec_entrypoint` so we manually
add the extract ESM output targets (this rule works with the aspect
and forwards linker mappings).
PR Close#48521
For every `ts_library` target we expose a shorthand that grants
access to the JS files because `DefaultInfo` of a ts library
only exposes the `.d.ts` files.
We rename this away from `es2015` since in practice it's a much
higher target these days. Additionally we no longer use the devmode
output but rather use the prodmode output which has the explicit
`.mjs` output- compatible with ESM.

Add a test to ensure that optimized image loaders can be configured at any
level of the DI hierarchy, including component's node injector.
PR Close#47565
Previously the built-in image loaders for the optimized image directive
were tightly coupled to the preconnect checks infrastructure. This was
creating a problem when developers were trying to provide a loader on
a component level (or, more generally, deeper in the DI hierarchy):
- PreconnectLinkChecker is the application-level service, provided in root;
- it makes sense to provide loaders in different parts of the DI hierarchy;
This refactoring removes the PreconnectLinkChecker configuration from
the loaders infrastructure and makes it application-wide config. The
PRECONNECT_CHECK_BLOCKLIST is also a simple provider (it was a
multi-provider previously) which should make the overall configuration
easier.

As an ongoing effort to stabilize the NgOptimizedImage API before existing the Developer Preview, this commit renames the `rawSrc` attribute used for the NgOptimizedImage selector matching to `ngSrc`. The `rawSrcset` is also renamed to `ngSrcset` for consistency.
The motivation for this change is to align the attribute name better with other built-in directives, such as `ngFor`, `ngIf`, `ngClass`, `ngStyle`, etc.
Note: this is technically a breaking change, but since the NgOptimizedImage directive is in the Developer Preview mode, we land the change in a patch branch.
