All the tests in `packages/core/test/view/` are specific to the `ViewEngine` and shouldn't run for ivy. This PR introduces a new BUILD.bazel file to run those tests separately.

In Ivy, a pure call to `setClassMetadata` is inserted to retain the
information that would otherwise be lost while eliding the Angular
decorators. In the past, the Angular constructor decorators were
wrapped inside of an anonymous function which was only evaluated once
`ReflectionCapabilities` was requested for such metadata. This approach
prevents forward references from inside the constructor parameter
decorators from being evaluated before they are available.
In the `setClassMetadata` call, the constructor parameters were not wrapped
within an anonymous function, such that forward references were evaluated
too early, causing runtime errors.
This commit changes the `setClassMetadata` call to pass the constructor
parameter decorators inside of an anonymous function again, such that
forward references are not resolved until requested by
`ReflectionCapabilities`, therefore avoiding the early reads of forward refs.

Currently the `ViewRef.destroy` method assumes that its index inside the view container will always be valid, however if it has been removed already, it'll be -1 which will throw an error.
The error manifested itself in one of the unit tests where a view had been detached during the test and then `TestBed` attempted to destroy its `ComponentRef` which ended threw an `Error during cleanup of component`.

Since Renderer is shared across root and child views, we need to avoid `destroy` method invocation for child views and only invoke is for root view when needed. Prior to this change, the `destroy` function was called whenever child view was destroyed, thus causing errors at runtime.

Previously in Ivy, host bindings did not work if they shared a public name
with an Input because they used the `elementProperty` instruction as is.
This instruction was originally built for inside component templates, so it
would either set a directive input OR a native property. This is the
correct behavior for inside a template, but for host bindings, we always
want the native properties to be set regardless of the presence of an Input.
This change adds an extra argument to `elementProperty` so we can tell it to
ignore directive inputs and only set native properties (if it is in the
context of a host binding).

In `ViewRef.detectChanges`, we are passing `ViewRef.context` into `detectChanges` to trigger change detection. This only makes sense for component `ViewRefs` (i.e. injected `ChangeDetectorRefs`) because with embedded views, `context` is not a component instance where the view has been monkey-patched. It's a just a normal object, so the view will be undefined.
In order to resolve this problem, we now invoke `detectChangesInternal` and also pass `LView` (to make sure we always have a view available).

We had two `NodeInjector` classes: one in `view_compatibility` and one in `di`. We replaced the one in `di` with the one from `view_compatibility` and reconciled their differences.

While generating attributes for `projection` instruction, we checked whether attribute name is equal to 'select' in lower case. However in other cases we treat 'select' attribute name as case-insensitive. This PR makes 'select' attribute consistently case-insensitive.

Prior to this change, animation properties were defined as element attributes, which caused errors at runtime. Now all animation-related attributes are defined as element properties.
Also as a part of this update, we start to account for bindings used in animations, which was previously missing.

Analogously to directives, the `ngInjectableDef` field in .d.ts files is
annotated with the type of service that it represents. If the service
contains required generic type arguments, these must be included in
the .d.ts file.

When an Injector is provided, R3Injector instantiates it by calling its
constructor instead of its factory, not resolving dependencies.
With this fix, the ngInjectorDef is checked and the factory is correctly
used if it is found.
PR Close#27456
When detaching a view by its index via `ViewContainerRef.detach(index)`, in `ViewEngine` we used to return a new `ViewRef` ([for reference](https://github.com/angular/angular/blob/master/packages/core/src/view/refs.ts#L227)), however in Ivy we return the same `ViewRef` which means that its internal `_viewContainerRef` is never reset and we'll throw an error if the consumer tried to attach it to the `ApplicationRef`. These changes return a new `ViewRef` in order to match the original behavior.
These changes also add the same errors as `ViewEngine` when attempting to attach a view that is attached already. This was the original goal of this PR, however it ended up uncovering the issues with the `ViewRef`.

Prior to this change, the number of host vars stored for directives with `hostBindings` in expando block was incorrect for inherited directives (in case both parent and child directive have `hostBindings` defined). Now if we identify that we already added a `hostBinding` into expando block, we just increase the corresponding number of host binding vars
