arturovt c49b28013a fix(animations): cleanup DOM elements when the root view is removed (#41059)
Currently, when importing `BrowserAnimationsModule`, Angular uses `AnimationRenderer`
as the renderer. When the root view is removed, the `AnimationRenderer` defers the actual
work to the `TransitionAnimationEngine` to do this, and the `TransitionAnimationEngine`
doesn't actually remove the DOM node, but just calls `markElementAsRemoved()`.

The actual DOM node is not removed until `TransitionAnimationEngine` "flushes".

Unfortunately, though, that "flush" will never happen, since the root view is being
destroyed and there will be no more flushes.

This commit adds `flush()` call when the root view is being destroyed.

BREAKING CHANGE:
DOM elements are now correctly removed when the root view is removed.
If you are using SSR and use the app's HTML for rendering, you will need
to ensure that you save the HTML to a variable before destorying the
app.
It is also possible that tests could be accidentally relying on the old behavior by
trying to find an element that was not removed in a previous test. If
this is the case, the failing tests should be updated to ensure they
have proper setup code which initializes elements they rely on.

Kristiyan Kostadinov 3c66b100dd perf(common): remove unused methods from DomAdapter (#41102)
The `DomAdapter` is present in all Angular apps and its methods aren't tree shakeable.
These changes remove the methods that either aren't being used anymore or were only
used by our own tests. Note that these changes aren't breaking, because the adapter
is an internal API.

The following methods were removed:
* `getProperty` - only used within our own tests.
* `log` - Guaranteed to be defined on `console`.
* `logGroup` and `logGroupEnd` - Only used in one place. It was in the DomAdapter for built-in null checking.
* `logGroupEnd` - Only used in one place. It was placed in the DomAdapter for built in null checking.
* `performanceNow` - Only used in one place that has to be invoked through the browser console.
* `supportsCookies` - Unused.
* `getCookie` - Unused.
* `getLocation` and `getHistory` - Only used in one place which appears to have access to the DOM
already, because it had direct accesses to `window`. Furthermore, even if this was being used
in a non-browser context already, the `DominoAdapter` was set up to throw an error.

The following APIs were changed to be more compact:
* `supportsDOMEvents` - Changed to a readonly property.
* `remove` - No longer returns the removed node.

JiaLiPassion dc9fd1aaef fix(core): NgZone coaleascing options should trigger onStable correctly (#40540)
fix https://github.com/angular/components/issues/21674

When setting `ngZoneRunCoalescing` to true, `onStable` is not emitted correctly.
the reason is before this commit, the code looks like this:

```
// application code call `ngZone.run()`
ngzone.run(() => {}); // step 1

// inside NgZone, in the OnInvoke hook, NgZone try to delay the checkStable()

function delayChangeDetectionForEvents(zone: NgZonePrivate) {
  if (zone.lastRequestAnimationFrameId !== -1) { // step 9
    return;
  }
  zone.lastRequestAnimationFrameId = zone.nativeRequestAnimationFrame.call(global, () => { // step 2
    if (!zone.fakeTopEventTask) {
      zone.fakeTopEventTask = Zone.root.scheduleEventTask('fakeTopEventTask', () => {
        zone.lastRequestAnimationFrameId = -1; // step 3
        updateMicroTaskStatus(zone); // step 4
        checkStable(zone); // step 6
      }, undefined, () => {}, () => {});
    }
    zone.fakeTopEventTask.invoke();
  });
  updatemicroTaskStatus(zone);
}

function updateMicroTaskStatus(zone: NgZonePrivate, ignoreCheckRAFId = false) {
  if (zone._hasPendingMicrotasks ||
      ((zone.shouldCoalesceEventChangeDetection || zone.shouldCoalesceRunChangeDetection) &&
       zone.lastRequestAnimationFrameId !== -1)) { // step 5
    zone.hasPendingMicrotasks = true;
  } else {
    zone.hasPendingMicrotasks = false;
  }
}

function checkStable(zone: NgZonePrivate) {
  if (zone._nesting == 0 && !zone.hasPendingMicrotasks && !zone.isStable) { // step 7
    try {
      zone._nesting++;
      zone.onMicrotaskEmpty.emit(null);
    ...
}

// application ref subscribe onMicroTaskEmpty
ngzone.onMicroTaskEmpty.subscribe(() => {
  ngzone.run(() => { // step 8
    tick();
  });
});

```

and the process is:
1. step 1: application call ngZone.run()
2. step 2: NgZone delay the checkStable() call in a requestAnimationFrame, and also set
zone.lastRequestAnimationFrameId
3. step 3: Inside the requestAnimationFrame callback, reset zone.lastRequestAnimationFrameId first
4. step 4: update microTask status
5, step 5: if zone.lastRequestAnimationFrameId is -1, that means no microTask pending.
6. step 6: checkStable and trigger onMicrotaskEmpty emitter.
7. step 7: ApplicationRef subscribed onMicrotaskEmpty, so it will call another `ngZone.run()` to process
tick()
8. step 8: And this new `ngZone.run()` will try to check `zone.lastRequestAnimationFrameId` in `step 9`
when trying to delay the checkStable(), and since the zone.lastRequestAnimationFrameId is already reset
to -1 in step 3, so this ngZone.run() will run into step 2 again.
9. and become a infinite loop..., so onStable is never emit

in this commit, there is a new flag `zone.isCheckStableRunning` added to
prevent re-entry when `shouldCoaleascing` flag is enabled.

JiaLiPassion 5e92d649f2 feat(core): add shouldCoalesceRunChangeDetection option to coalesce change detections in the same event loop. (#39422)
Close #39348

Now `NgZone` has an option `shouldCoalesceEventChangeDetection` to coalesce
multiple event handler's change detections to one async change detection.

And there are some cases other than `event handler` have the same issues.
In #39348, the case like this.

```
// This code results in one change detection occurring per
// ngZone.run() call. This is entirely feasible, and can be a serious
// performance issue.
for (let i = 0; i < 100; i++) {
  this.ngZone.run(() => {
    // do something
  });
}
```

So such kind of case will trigger multiple change detections.
And now with Ivy, we have a new `markDirty()` API will schedule
a requestAnimationFrame to trigger change detection and also coalesce
the change detections in the same event loop, `markDirty()` API doesn't
only take care `event handler` but also all other cases `sync/macroTask/..`

So this PR add a new option to coalesce change detections for all cases.

Adrian Rutkowski c8f056beb6 fix(core): ensure TestBed is not instantiated before override provider (#38717)
There is an inconsistency in overrideProvider behaviour. Testing documentation says
(https://angular.io/guide/testing-components-basics#createcomponent) that all override...
methods throw error if TestBed is already instantiated. However overrideProvider doesn't throw any error, but (same as
other override... methods) doesn't replace providers if TestBed is instantiated. Add TestBed instantiation check to
overrideProvider method to make it consistent.

BREAKING CHANGE:

If you call `TestBed.overrideProvider` after TestBed initialization, provider overrides are not applied. This
behavior is consistent with other override methods (such as `TestBed.overrideDirective`, etc) but they
throw an error to indicate that, when the check was missing in the `TestBed.overrideProvider` function.
Now calling `TestBed.overrideProvider` after TestBed initialization also triggers an
error, thus there is a chance that some tests (where `TestBed.overrideProvider` is
called after TestBed initialization) will start to fail and require updates to move `TestBed.overrideProvider` calls
before TestBed initialization is completed.

JiaLiPassion 284123c6ba fix(core): should fake a top event task when coalescing events to prevent draining microTaskQueue too early. (#36841)
Close #36839.

This is a known issue of zone.js,

```
(window as any)[(Zone as any).__symbol__('setTimeout')](() => {
  let log = '';
  button.addEventListener('click', () => {
    Zone.current.scheduleMicroTask('test', () => log += 'microtask;');
    log += 'click;';
  });
  button.click();
  expect(log).toEqual('click;microtask;');
  done();
});
```

Since in this case, we use native `setTimeout` which is not a ZoneTask,
so zone.js consider the button click handler as the top Task then drain the
microTaskQueue after the click at once, which is not correct(too early).

This case was an edge case and not reported by the users, until we have the
new option ngZoneEventCoalescing, since the event coalescing will happen
in native requestAnimationFrame, so it will not be a ZoneTask, and zone.js will
consider any Task happen in the change detection stage as the top task, and if
there are any microTasks(such as Promise.then) happen in the process, it may be
drained earlier than it should be, so to prevent this situation, we need to schedule
a fake event task and run the change detection check in this fake event task,
so the Task happen in the change detection stage will not be
considered as top ZoneTask.

Alan Agius 64d6f13b87 fix(platform-browser): add missing peerDependency on `@angular/animations` (#35949)
`@angular/platform-browser/animations` has a dependency on `@angular/animations` however, this is not listed in `peerDependencies`

With this change we add this package as an optional peerDependency as it's only required when using the `@angular/platform-browser/animations` entrypoint.

Fixes #35888

Andrew Scott d543b13e5c Revert "fix(core): log error instead of warning for unknown properties and elements (#35798)" (#35845)
This reverts commit 00f3c58bb9.
Rolling back because it could be breaking e2e tests that assert that
there are no errors in the console after the assertions have run. We can
re-add this in v10.

crisbeto 00f3c58bb9 fix(core): log error instead of warning for unknown properties and elements (#35798)
Changes the Ivy unknown element/property messages from being logged with `console.warn` to `console.error`. This should make them a bit more visible without breaking existing apps. Furthermore, a lot of folks filter out warning messages in the dev tools' console, whereas errors are usually still shown.

Fixes #35699.

Rado Kirov 294e56d529 refactor(platform-browser): Hoist functions to workaround optimization bug. (#32230)
Technically, function definitions can live anywhere because they are
hoisted. However, in this case Closure optimizations break when exported
function definitions are referred in another static object that is
exported.

The bad pattern is:
```
exports const obj = {f};
export function f() {...}
```

which turns to the following in Closure's module system:
```
goog.module('m');

exports.obj = {f};

function f() {...}
exports.f = f;
```

which badly optimizes to (note module objects are collapsed)
```
var b = a; var a = function() {...};  // now b is undefined.
```

This is an optimizer bug and should be fixed in Closure, but in the
meantime this change is a noop and will unblock other changes we want to
make.
