To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.
Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:
ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

Adds support for TypeScript 4.5. Includes the following changes:
* Bumping the package versions.
* Fixing a few calls to `createExportSpecifier` and `createImportSpecifier` that require an extra parameter.
* Adding some missing methods to the TS compiler hosts.
* Fixing an issue in the TS mocks for the ngcc tests where a regex was too agressive and was trying to match a path like `/node_modules/@typescript/lib-es5`.
* Accounting for type-only import specifiers when reporting DI errors (see #43620).
Fixes#43620.

With this change we update `rollup` and remove the usage of no longer maintained `rollup-plugin-commonjs` and `rollup-plugin-node-resolve` plugins.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `[email protected]` and `[email protected]`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

Introduce two new bazel rules: tsec_test and tsec_config, for
describing the tsec checks and the tsconfig file needed for such
checks, respectively. Currently, tsec_test only checks the srcs
of a ts_library or ng_module. It does not check direct or transitive
dependencies. Also, tsconfig files need to be manually maintained
to make sure tsec can read all necessary input (including global
symbols).

tsec is a static analyzer that discovers Trusted Types violations.
Deploy tsec to make sure there will be no TT regression in several
critical packages, including core, platform-browser, platform-server
and their dependencies. Existing violations have been reviewed and
exempted in packages/tsec-exemption.json. Future changes to the
exemption list requires security review.

The current naming causes tsickle to emit `/** @implements {ZoneDelegate} */ class ZoneDelegate ...`, which is a cyclic definition error in Closure Compiler. Additionally, the name shadowing is also confusing to humans.

In the previous commit https://github.com/angular/angular/pull/41562#issuecomment-822696973,
the error thrown in the event listener will be caught and re-thrown, but there is a bug
in the commit, if there is only one listener for the specified event name, the error
will not be re-thrown, so this commit fixes the issue and make sure the error is re-thrown.

Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

This change moves the `dev-infra/browsers` folder into `dev-infra/bazel`.
The browser folder is providing custom configuration for Bazel, so it
should live within the `bazel` folder for a more well-structured

zone.js invoke all `onload` event handlers before change the XHR task's state from
`scheduled` to `notscheduled`, so if any `onload` listener throw error, the XHR task
wlll be hang to `scheduled`, and leave the macroTask status in the zone wrongly.
This has been fixed in the previous commit, this commit add test to verify the case.

`zone.js` patches event listeners and run all event listeners together, if
one event handler throws error, the listeners afterward may not be invoked.
Reproduction:
```
export class AppComponent implements AfterViewInit {
@ViewChild('btn') btn: ElementRef;
title = 'event-error';
constructor(private ngZone: NgZone) {}
ngAfterViewInit() {
this.ngZone.runOutsideAngular(() => {
this.btn.nativeElement.addEventListener('click', () => {
throw new Error('test1');
});
this.btn.nativeElement.addEventListener('click', () => {
console.log('add eventlistener click');
});
});
}
}
```
Until now no Angular users report this issue becuase in the `ngZone`, all
error will be caught and will not rethrow, so the event listeners afterward
will still continue to execute, but if the event handlers are outside of `ngZone`,
the error will break the execution.
This commit catch all errors, and after all event listeners finished invocation,
rethrow the errors in seperate `microTasks`, the reason I am using `microTask` here
is to handle multiple errors case.
