With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.
**Before**
```ts
import {XhrFactory} from '@angular/common/http';
```
**After**
```ts
import {XhrFactory} from '@angular/common';

A long-requested feature for HttpClient is the ability to store and retrieve
custom metadata for requests, especially in interceptors. This commit
implements this functionality via a new context object for requests.
Each outgoing HttpRequest now has an associated "context", an instance of
the HttpContext class. An HttpContext can be provided when making a request,
or if not then an empty context is created for the new request. This context
shares its lifecycle with the entire request, even across operations that
change the identity of the HttpRequest instance such as RxJS retries.
The HttpContext functions as an expando. Users can create typed tokens as instances of HttpContextToken, and
read/write a value for the key from any HttpContext object.
This commit implements the HttpContext functionality. A followup commit will
add angular.io documentation.

The custom elements spec is not compatible with ES5 style classes. This
means ES2015 code compiled to ES5 will not work with a native
implementation of Custom Elements. To support browsers that natively
support Custom Elements but not ES2015 modules, we load
`@webcomponents/custom-elements/src/native-shim.js`, which minimally
augments the native implementation to be compatible with ES5 code.
(See [here][1] for more details.)
Previously, the shim was included in `polyfills.ts`, which meant it was
loaded in all browsers (even those supporting ES2015 modules and thus
not needing the shim).
This commit moves the shim from `polyfills.ts` to a `nomodule` script
tag in `index.html`. This will ensure that it is only loaded in browsers
that do not support ES2015 modules and thus do not needed the shim.
NOTE:
This commit also reduces size of the polyfills bundle by ~400B
(52609B --> 52215B).

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.

Previously, injector definitions contained a `factory` property that
was used to create a new instance of the associated NgModule class.
Now this factory has been moved to its own `ɵfac` static property on the
NgModule class itself. This is inline with how directives, components and
pipes are created.
There is a small size increase to bundle sizes for each NgModule class,
because the `ɵfac` takes up a bit more space:
Before:
```js
let a = (() => {
class n {}
return n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({factory: function(t) { return new (t || n) }, imports: [[e.a.forChild(s)], e.a]}),
n
})(),
```
After:
```js
let a = (() => {
class n {}
return n.\u0275fac = function(t) { return new (t || n) },
n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({imports: [[r.a.forChild(s)], r.a]}),
n
})(),
```
In other words `n.\u0275fac = ` is longer than `factory: ` (by 5 characters)
and only because the tooling insists on encoding `ɵ` as `\u0275`.
This can be mitigated in a future PR by only generating the `ɵfac` property
if it is actually needed.

Currently `NgTemplateOutlet` recreates its view if its template is swapped out or a context
object with a different shape is passed in. If an object with the same shape is passed in,
we preserve the old view and we mutate the previous object. This mutation of the original
object can be undesirable if two objects with the same shape are swapped between two
different template outlets.
The current behavior is a result of a limitation in `core` where the `context` of an embedded
view is read-only, however a previous commit made it writeable.
These changes resolve the context mutation issue and clean up a bunch of unnecessary
logic from `NgTemplateOutlet` by taking advantage of the earlier change.

The injector system uses a bloom filter to determine if a token is
possibly defined in the node injector tree, which is stored across
multiple bloom buckets that each represent 32 bits of the full 256-bit
wide bloom hash. This means that a computation is required to determine
the exact bloom bucket which is responsible for storing any given 32-bit
interval, which was previously computed using three bitmask operations
and three branches to derive the bloom bucket offset.
This commit exploits the observation that all bits beyond the low 5 bits
of the bloom hash are an accurate representation for the bucket offset,
if shifted right such that those bits become the least significant bits.
This reduces the three bitmask operations and three branches with a
single shift operation, while additionally offering a code size
improvement.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

Occasionally, the SW would end up in a broken state where some of the
eagerly cached resources of an older version were available in the local
cache, but others (such as lazy-loaded bundles) were not. This would
leave the app in a broken state and a blank screen would be displayed.
See #28114 for a more detailed discussion.
This commit takes advantage of the newly introduced (in v11)
[SwUpdate#unrecoverable][1] API to detect these bad states and recover
by doing a full page reload whenever an [UnrecoverableStateEvent][2] is
emitted.
Partially addresses #28114.
NOTE:
Currently, `SwUpdate.unrecoverable` only works if the app has already
bootstrapped; i.e. if only lazy-loaded bundles have been purged from the
cache.
That should be fine in practice, since the cache entries are removed in
least-recently-used order. Thus the eagerly loaded bundles will be the
last to be removed from the cache (which rarely happens in practice).

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.

In ViewEngine, SelfSkip would navigate up the tree to get tokens from
the parent node, skipping the child. This restores that functionality in
Ivy. In ViewEngine, if a special token (e.g. ElementRef) was not found
in the NodeInjector tree, the ModuleInjector was also used to lookup
that token. While special tokens like ElementRef make sense only in a
context of a NodeInjector, we preserved ViewEngine logic for now to
avoid breaking changes.
We identified 4 scenarios related to @SkipSelf and special tokens where
ViewEngine behavior was incorrect and is likely due to bugs. In Ivy this
is implemented to provide a more intuitive API. The list of scenarios
can be found below.
1. When Injector is used in combination with @Host and @SkipSelf on the
first Component within a module and the injector is defined in the
module, ViewEngine will get the injector from the module. In Ivy, it
does not do this and throws instead.
2. When retrieving a @ViewContainerRef while @SkipSelf and @Host are
present, in ViewEngine, it throws an exception. In Ivy it returns the
host ViewContainerRef.
3. When retrieving a @ViewContainerRef on an embedded view and @SkipSelf
is present, in ViewEngine, the ref is null. In Ivy it returns the parent
ViewContainerRef.
4. When utilizing viewProviders and providers, a child component that is
nested within a parent component that has @SkipSelf on a viewProvider
value, if that provider is provided by the parent component's
viewProviders and providers, ViewEngine will return that parent's
viewProviders value, which violates how viewProviders' visibility should
work. In Ivy, it retrieves the value from providers, as it should.
These discrepancies all behave as they should in Ivy and are likely bugs
in ViewEngine.
