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.

when reordering a list with animations the list items lose their current
triggers values, that is because the reordering of an item is implemented
as follows (_note:_ the following implementation has been added in PR #23534)
- the item is removed and marked _setForRemoval_
- the item is re-inserted, and the _setForRemoval_ is changed to _setForMove_
- the player set for animating the removal is destroyed when _setForMove_ is detected
the above steps allow the element not to be animated and to keep its styling but the
triggers values get lost since the removal transition/player has already been initialized,
so this change adds a _previousTriggersValues_ map in the _REMOVAL_FLAG_ field in order to
restore the triggers values if/when the removal turns out to be a move, changing the above steps to:
- the item is removed and marked setForRemoval __and its current triggers values are saved as well__
- the item is re-inserted, and the setForRemoval is changed to setForMove
- the player set for animating the removal is destroyed when setForMove is detected __and the
trigger values are re-applied in the engine's statesByElement map__

* 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`.

Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.
Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.
Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!

the final styles created in buildStyles lack normalization, meaning that pixel values remain as numbers (without "px") and so such properties fail to be correctly set/applied

When including a component in a template, the component's host element
is immediately appended as child of the parent node upon creation.
Hence, `hostElement.parentNode` will be a valid reference. However, if
the parent component is being inserted as an embedded view—through
`ngIf` for example—then the parent's node itself will not have been
inserted yet. This means that we cannot properly determine the position
of the transition namespace, as any `containsElement` check will return
false given that the partial DOM tree has not been inserted yet, even
though it will be contained within an existing transition namespace once
the partial tree is attached.
This commit fixes the issue by not just looking at the existence of a
parent node, but rather a more extensive check using the driver's
`containsElement` method.

Currently the only way to disable animations is by providing the `NoopAnimationsModule`
which doesn't allow for it to be disabled based on runtime information. These changes
add support for disabling animations based on runtime information by using
`BrowserAnimationsModule.withConfig({disableAnimations: true})`.

Prior to this patch, if an element was removed multiple times (due
to the nature of parent/child elements), the leave listeners may
have been fired for an element that was already removed. This patch

In #28162 we introduced an extra `removeNode` call for host elements which can cause the parent element to be removed before all child animations have finished. The issue is only in Ivy, because that the only place where we pass in the `isHostElement` flag. These changes fix the issue by not re-triggering the removal logic if the element has in-progress animations.
Fixes#33597.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

When web-animations and/or CSS keyframes are used for animations certain
CSS style values (such as `display` and `position`) may be ignored by a
keyframe-based animation. Angular should special-case these styles to
ensure that they get applied as inline styles throughout the duration of
the animation.

Due to the fast moving nature of the Ivy codebase, the timing isn't
right to make changes to how errors and reported and handled during the
runtime.
Once ivy is stable this test should be revisted because that stage there
will be a better and more robust understanding of how ivy should recover
from runtime errors.

Due to the fact that animations in Angular are defined in the component metadata,
all animation trigger definitions are localized to the component and are
inaccessible outside of it. Animation host listeners in Ivy are
rendered in the context of the parent component, but the VE renders them
differently. This patch ensures that animation host listeners are
always registered in the sub component's renderer

Prior to this fix Ivy would not execute any animation triggers
that exist as host bindings on an element if it is removed by
the parent template.
PR Close#28162
In Ivy when elements are created a series of static attribute names are provided
over to the construction instruction of that element. Static attribute names
include non-binding attribues (like `<div selected>`) as well as animation bindings
that do not have a RHS value (like `<div @foo>`). Because of this distinction,
value-less animation triggers are rendered first before value-full animation
bindings are and this improper ordering has caused various existing tests to fail.
This patch ensures that animation bindings are evaluated in the order that they
exist within the HTML template code (or host binding code).

Some of the animation tests have been failing because animation gets
triggered multiple times. The reason for this is that the compiler was

This created multiple writes to the animation render which failed the

Prior to this commit, we had two different modes for change detection
execution for Ivy, depending on whether you called `bootstrap()` or
`renderComponent()`. In the former case, we would complete creation
mode for all components in the tree before beginning update mode for
any component. In the latter case, we would run creation mode and
update mode together for each component individually.
Maintaining code to support these two different execution orders was
unnecessarily complex, so this commit aligns the two bootstrapping
mechanisms to execute in the same order. Now creation mode always
runs for all components before update mode begins.
This change also simplifies our rendering logic so that we use
`LView` flags as the source of truth for rendering mode instead of
`rf` function arguments. This fixed some related bugs (e.g. calling
`ViewRef.detectChanges` synchronously after the view's creation
would create view nodes twice, view queries would execute twice, etc).
