This commit expands the info printed to the console to help diagnose
ServiceWorker issues to include the [internal debug info][1] retrieved
from `/ngsw/state`. This will provide more useful data, such as the
activated SW's version, state, clients, recent operations and any recent
errors.
NOTE:
This temporarily increases the payload size. Removing this code and
reclaiming the payload size is being tracked in #41117.

xi18n is the operation of extracting i18n messages from templates in the
compilation. Previously, only View Engine was able to perform xi18n. This
commit implements xi18n in the Ivy compiler, and a copy of the View Engine
test for Ivy verifies that the results are identical.

Previously, the `NotificationComponent` would be hidden by reducing its
height to `0`. This allowed for a smoother hide animation when closing
the notification, but left the component's interactive elements
focusable via keyboard navigation. This was confusing for users, because
the focused elements would not be visible on the page.
This commit fixes the issue be also setting the `display` CSS property
to `none` when the `NotificationComponent` is hidden, thus ensuring that
its contents are not focusable via keyboard navigation.
(This does not affect the hide animation, since the `display` style is
not animatable and is only applied at the end of the animation.)

Previously, we included a dummy `MatIcon` element in `AppComponent` in
order to ensure that the `Material Icons` font would be requested (and
thus cached by the ServiceWorker) on every navigation. However, #41129
introduced the `ThemeToggleComponent`, which will be present on all
pages (since it is located in the top-menu) and relies on the
`Material Icons` font. Therefore, the work-around for loading the
`Material Icons` font is no longer necessary.
This commit removes the now redundant `MatIcon` from `AppComponent`.

This commit changes the anchor elements used for external links to
`MatIconButton`s. While the appearance remains the same (with the
exception of hover/focus styles), this better aligns the styling of
external link icons with other nearby icon buttons (i.e. the theme
toggle) and alows as to simplify the CSS for external links (since much
of their styling is handled by Angular Material).
PR Close#42584
Since we now use SVG for external link icons, there are no `<img>`
elements inside the anchor elements. So, the CSS rule does not match any
element and can be removed.

Previously, we only tracked the sizes of the eagerly loaded JS bundles.
However, the CSS styles (which also have a non-negligible size) must
also be downloaded and parsed by the browser, thus affecting the initial

We currently have two long-standing issues related to how `TestBed` tests are torn down:
1. The dynamically-created test module isn't going to be destroyed, preventing the `ngOnDestroy` hooks on providers from running and keeping the component `style` nodes in the DOM.
2. The test root elements aren't going to be removed from the DOM. Instead, they will be removed whenever another test component is created.
By themselves, these issues are easy to resolve, but given how long they've been around, there are a lot of unit tests out there that depend on the broken behavior.
These changes address the issues by introducing APIs that allow users to opt into the correct test teardown behavior either at the application level via `TestBed.initTestEnvironment` or the test suite level via `TestBed.configureTestingModule`.
At the moment, the new teardown behavior is opt-in, but the idea is that we'll eventually make it opt-out before removing the configuration altogether.

This commit adds a popup to angular.io to inform the user about the use
of cookies. Once the user confirms having read the info, the popup will
not be shown on subsequent visits.
This commit is partly based on angular/material.angular.io#988.
Fixes#42209
PR Close#42259
Previously, we had the same logic in a couple of places to safely access
the `Window`'s `local-/sessionStorage` and provide a no-op fallback if
necessary. Soon, we will need the same logic for the cookies popup
(see #42209).
This commit reduces code duplication by providing
`local-/sessionStorage` as injectables and sharing the logic for
accessing them safely. This also makes it easier to mock the storage in
tests without having to mess with the actual `Window` object.
NOTE:
This commit actually decreases the payload size in the `main` bundle by
40B.

This commit aligns the angular.io config files more closely to how a
newly generated CLI v12 app would look like. This helps validate the
setup and makes it easier to apply new chages in the future (by

default new app layout).

We can’t determine whether the user actually meant the `back` or
the `forward` using the popstate event (triggered by a browser
back/forward)
so we instead need to store information on the state and compute the
distance the user is traveling withing the browser history.
So by using the `History#go` method,
we can bring the user back to the page where he is supposed to be after
performing the action.

As previously discussed in pull/31070 and issues/30486, this would be useful because it is often desirable to apply styles to fields that are both `ng-invalid` and `ng-pristine` after the first attempt at form submission, but Angular does not provide any simple way to do this (although evidently Angularjs did). This will now be possible with a descendant selector such as `.ng-submitted .ng-invalid`.
In this implementation, the directive that sets control status classes on forms and formGroups has its set of statuses widened to include `ng-submitted`. Then, in the event that `is('submitted')` is invoked, the `submitted` property of the control container is returned iff it exists. This is preferred over checking whether the container is a `Form` or `FormGroup` directly to avoid reflecting on those classes.

This is based on a discussion we had a few weeks ago. Currently if a component uses `ViewEncapsulation.ShadowDom` and its selector doesn't meet the requirements for a custom element tag name, a vague error will be thrown at runtime saying something like "Element does not support attachShadowRoot".
These changes add a new diagnostic to the compiler that validates the component selector and gives a better error message during compilation.

Makes the following improvements to the listener instructions to make them slightly smaller and more memory-efficient.
1. Removes the default value from the `useCapture` parameter since it generates more code than just castint to `false`.
2. Removes the `useCapture` and `eventTargetResolver` parameters from `ɵɵsyntheticHostListener` since they won't be generated by the compiler, as far as I can tell.
3. Makes it so that we don't have to return a target name from a `GlobalTargetResolver`. This allows us to save on some memory, because we can return a reference to the target without having to wrap it in an object literal.
DEPRECATIONS:
`EventManagerPlugin.getGlobalEventTarget` is now deprecated and won't be called from Ivy code anymore. Global events will go through `addEventListener`.
PR Close#41807
Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving
the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to
the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has
references to all of the child nodes of the view, as well as other internal data structures.
Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed
(see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can
slow down destruction due to a megamorphic write.
These changes aim to address the issue while reducing the performance impact by assigning a unique
ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in
a map where their unique ID is used as the key. We don't need to worry about leaks within that map,
because `LView`s are an internal data structure and we have complete control over when they are
created and destroyed.

When determining whether to run an animation, the `TransitionAnimationPlayer`
checks to see if a DOM element is attached to the document. This is done by
checking to see if the element is "contained" by the document body node.
Previously, if the element was inside a shadow DOM, the engine would
determine that the element was not attached, even if the shadow DOM's
host was attached to the document. This commit updates the `containsElement()`
method on `AnimationDriver` implementations to also include shadow DOM
elements as being contained if their shadow host element is contained.
Further, when using CSS keyframes to trigger animations, the styling
was always added to the `head` element of the document, even for
animations on elements within a shadow DOM. This meant that those
elements never receive those styles and the animation would not run.
This commit updates the insertion of these styles so that they are added,
to the element's "root node", which is the nearest shadow DOM host, or the
`head` of the document if the element is not in a shadow DOM.

This commit marks the `compilationMode` compiler option as stable, such
that libraries can be compiled in partial compilation mode.
In partial compilation mode, the compiler's output changes from fully
compiled AOT definitions to an intermediate form using partial
declarations. This form is suitable to be published to NPM, which now
allows libraries to be compiled and published using the Ivy compiler.
Please be aware that libraries that have been compiled using this mode
can only be used in Angular 12 applications and up; they cannot be used
when Ivy is disabled (i.e. when using View Engine) or in versions of
Angular prior to 12. The `compilationMode` option has no effect if
`enableIvy: false` is used.
