These helpers are often imported by various tests throughout the
repository, but the helpers aren't exported/exposed from the public
entry-point; even though they confusingly reside in there.
This commit fixes this, and moves the helpers into
`packages/private/testing`. This is a preparation for the `ts_project`
migration where we don't want to leverage deep imports between packages.

`provideLazyLoadedAnimations()` returns providers which allow the lazy loading of the animation module.
Lazy loading of the animation code can shave off up to 16KB gzipped of the main bundle.

The `NoopAnimationDriver` as static property of `AnimationDriver` prevents it from being removed by tree shaking. This commit deprecates it and exposes the `NoopAnimationDriver` on the public API to replace its usage.
DEPRECATED:
The `AnimationDriver.NOOP` symbol is deprecated, use `NoopAnimationDriver` instead.
PR Close#51843
The animations packages were duplicating a little bit of code due
to relative imports between entry-points. This caused bundlers to
inline shared functions twice in both FESM outputs.

The prior approach would consider all existing namespaces from back to front
to find the one that's the closest ancestor for a given host element. An
expensive `contains` operation was used which needed to traverse all the
way up the document root _for each existing namespace_. This commit implements
an optimization where the closest namespace is found by traversing up from
the host element, avoiding repeated DOM traversal.

This commit removes CSS keyframes-based code that was used to support animations in old browsers. With IE11 deprecation, all supported browsers have native WebAnimations support, so the old code can be removed. This results in ~7KB decrease of the animations package bundle size, since most of the code was non-tree-shakable.
Closes#44520.

We were using a number of generic objects as if they were maps and relying on delete to remove
properties. In order to improve performance, these have been switched to native maps.

* The `TransitionAnimationEngine` had a fallback where it would store classes directly on a node if it doesn't have a `classList`. Presumably this is to support old browsers or if an animation is set on something like `ng-container`. This information was never used for anything since `containsClass` was never called. These changes simplify the logic to just a null check.
* Deprecates the `AnimationDriver.matchesElement` method, because it was only used in one place which can be replaced with `classList.contains`. We can't remove the method completely, because `AnimationDriver` is a public API. We also can't turn it into a method on the base class in order to remove it from the sub-classes, because it can break apps using `noImplicitOverride` while extending `AnimationDriver`.

ɵAnimationDriver can be safely removed from private exports as AnimationDriver
is already a public export. Since its already available, we can safely remove
its declaration and migrate its only usage in our repo to rely on the public
AnimationDriver symbol.

We now create npm packages to cover all the public api assertions in tools/public_api_guard.
We no longer depend on ts-api-guardian from npm - it is now stale since the repository was archived.
There is no longer a gulp task to enforce or accept the public API, this is in CircleCI as part of running all bazel test targets.

This patch removes the need to include the Web Animations API Polyfill
(web-animations-js) as a dependency. Angular will now fallback to using
CSS Keyframes in the event that `element.animate` is no longer supported
by the browser.
In the event that an application does use `AnimationBuilder` then the
web-animations-js polyfill is required to enable programmatic,
position-based access to an animation.
