`Location.go` does not trigger the browser's `popstate` event because
the Angular Router uses `pushState` and `replaceState`. This can be
confusing when calling `Location.go` and using `Location.subscribe`.
This commit clarifies the behavior of `Location.subscribe` and points
developers to the `onUrlChanges` subscription instead.

The `ViewportScroller` figures out which element to scroll into view using `document.getElementById`. The problem is that it won't find elements inside the shadow DOM.
These changes add some extra logic that goes through all the shadow roots to look for the element.
Fixes#41470.

Add new method `historyGo`, that will let
the user navigate to a specific page from session history identified by its
relative position to the current page.
We add some tests to `location_spec.ts` to validate the behavior of the
`historyGo` and `forward` methods.
Add more tests for `location_spec` to test `location.historyGo(0)`, `location.historyGo()`,
`location.historyGo(100)` and `location.historyGo(-100)`. We also add new tests for
`Integration` spec to validate the navigation when we using
`location#historyGo`.
Update the `historyGo` function docs
Note that this was made an optional function in the abstract classes to
avoid a breaking change. Because our location classes use `implements PlatformLocation`
rather than `extends PlatformLocation`, simply adding a default
implementation was not sufficient to make this a non-breaking change.
While we could fix the classes internal to Angular, this would still have been
a breaking change for any external developers who may have followed our
implementations as an example.

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';
```

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.

This is necessary for closure compiler in order to support cross chunk code motion.
I'm intentionally not annotating these call sites with @__PURE__ at the moment because
build-optimizer does it within the Angular CLI build. In the future we might want to consider
having both annotations here in case we change how build-optimizer works.

In the new behavior Angular cleanups `popstate` and `hashchange` event listeners
when the root view gets destroyed, thus event handlers are not added twice
when the application is bootstrapped again.
BREAKING CHANGE:
Methods of the `PlatformLocation` class, namely `onPopState` and `onHashChange`,
used to return `void`. Now those methods return functions that can be called
to remove event handlers.

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.

This commit adds support for Finnish full date formatting,
as well as `c/cc/ccc/cccc/ccccc/cccccc` date formats in the `DatePipe`.
Fixes#26922
PR Close#40766
In b6cd38ff05 we fixed the DatePipe so
that when it parsed date strings that looked like `YYYY-MM` it created a UTC
date that was not affected by the local timezone of the JavaScript engine.
This commit does the same for date strings of the form `YYYY`.
(Note that the previous commit, mentioned above, attempted to fix this case
too but the test was not actually checking the correct input string.)

According to the [spec](https://html.spec.whatwg.org/#scroll-to-fragid),
we should attempt to set the browser focus after scrolling to a
fragment. Note that this change does not exactly follow the robust steps
outlined in the spec by finding a fallback target if the original is not
focusable. Instead, we simply attempt to focus the element by calling
`focus` on it, which will do nothing if the element is not focusable.

This commit adds ngDevMode guard to show warnings only
in dev mode (similar to how things work in other parts of Ivy runtime code).
The ngDevMode flag helps to tree-shake these warnings from production builds
(in dev mode everything will work as it works right now) to decrease production bundle size.
