`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.

With this change we update several dependencies to avoid Renovate creating a lot of PRs during onboarding. We also remove yarn workspaces as after further analysis these are not needed.
Certain dependencies such as `@octokit/rest`, `remark` and `@babel/*` have not been updated as they require a decent amount of work to update, and it's best to leave them for a seperate PR.

With this change we drop support for zone.js 0.10.x.
This is needed because in version 12 the CLI will only work with `~0.11.4`. See angular/angular-cli#20034.
BREAKING CHANGE:
Minimum supported `zone.js` version is `0.11.4`
PR Close#40823
Close#40387
Currently zone.js patches `setTimeout` and keeps a `tasksByHandleId` map to keep `timerId` <-> `ZoneTask`
relationship. This is needed so that when `clearTimeout(timerId)` is called, zone.js can find the associated
`ZoneTask`. Now zone.js set the `tasksByHandleId` map in the `scheduleTask` function, but if the `setTimeout`
is running in the `FakeAsyncZoneSpec` or any other `ZoneSpec` with `onScheduleTask` hooks. The `scheduleTask`
in `timer` patch may not be invoked.
For example:
```
fakeAsync(() => {
setTimeout(() => {});
tick();
});
```
In this case, the `timerId` kept in the `tasksByHandleId` map is not cleared.
This is because the `FakeAsyncZoneSpec` in the `onScheduleTask` hook looks like this.
```
onScheduleTask(delegate, ..., task) {
fakeAsyncScheduler.setTimeout(task);
return task;
}
```
Because `FakeAsyncZoneSpec` handles the task itself and it doesn't call `parentDelegate.onScheduleTask`,
therefore the default `scheduleTask` in the `timer` patch is not invoked.
In this commit, the cleanup logic is moved from `scheduleTask` to `setTimeout` patch entry to
avoid the memory leak.

When migrating zone.js from gulp to bazel, some legacy build config files are still there,
we have `rollup-es5.config.js` and `rollup-es5_global-es2015.config.js`, since in gulp build
system, build `es5` or `esm` files are set in the config file, but in the bazel world,
the output format is not config in the config.js file, but is required by the downstream
bazel target. So we don't really need the two rollup config files any longer.
Another difference is in `rollup-es5.config.js`, the `external` and `global` libraries names
are also config there, and these settings are also valid for `es2015` build, these settings
are not in the `es2015.config.js` for some legacy reasons. So we don't need to keep this
difference either.
PR Close#40481
Close#40215
`fesm2015/zone.js` is built to `esm` bundle with rollup, so the 'use strict';
statement is not generated in the bundle, even we put the 'use strict' in the src code,
rollup removes the code in the final bundle.
So if we load the `fesm2015/zone.js` as a module, such as `ng serve`, in the index.html
```
<script src="polyfills.js" type="module"></script>
```
Everything works fine, since polyfills.js is loaded as `module`, so it is always `strict`.
But in `ng test`, webpack concat the `zone.js` and loaded into the karma html. For other app and
test code, they are still `strict` since they are `module` because they have `export/import`
statement, but `zone.js` is a bundle without `export`, it is a `side effect` bundle, so after
loaded by webpack, it becomes non-strict. Which causes some issues, such as #40215,
the root cause is the `this` context should be `undefined` but treated as `Window` in `non-strict` mode.
```
Object.prototype.toString.apply(undefined);
// should be [object undefined], but it is [object Window] in non-strict mode.
// zone.js patched version of toString
Object.prototype.toString = function() {
...
// in non-strict mode, this is Window
return originalObjectPrototypeToString.call(this);
}
```
So in this commit, `'use strict';` is always added to the `esm` bundles.

`zone.js` 0.8.25 introduces `zone-testing` bundle and move all `fakeAsync/async` logic
from `@angular/core/testing` to `zone.js` package. But in case some user still using the old
version of `zone.js`, an old version of `fakeAsync/async` logic were still kept inside `@angular/core/testing`

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.
Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0
Features of note for angular/angular:
* stdout/stderr/exit code capture; this could be potentially be useful
* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
heavy weight
Breaking changes of note for angular/angular:
* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
(which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`
* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.
* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
`@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
`@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
internals for ng_module.
* runfiles.resolve will now throw instead of returning undefined to match behavior of node require
Other changes in angular/angular:
* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.
NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.
* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

Close#38851, support `jest` fakeTimers APIs' integration with `fakeAsync()`.
After enable this feature, calling `jest.useFakeTimers()` will make all test
run into `fakeAsync()` automatically.
```
beforeEach(() => {
jest.useFakeTimers('modern');
});
afterEach(() => {
jest.useRealTimers();
});
test('should run into fakeAsync() automatically', () => {
const fakeAsyncZoneSpec = Zone.current.get('FakeAsyncTestZoneSpec');
expect(fakeAsyncZoneSpec).toBeTruthy();
});
```
Also there are mappings between `jest` and `zone` APIs.
- `jest.runAllTicks()` will call `flushMicrotasks()`.
- `jest.runAllTimers()` will call `flush()`.
- `jest.advanceTimersByTime()` will call `tick()`
- `jest.runOnlyPendingTimers()` will call `flushOnlyPendingTimers()`
- `jest.advanceTimersToNextTimer()` will call `tickToNext()`
- `jest.clearAllTimers()` will call `removeAllTimers()`
- `jest.getTimerCount()` will call `getTimerCount()`
