Integrate ActivityTransitionAnimator in CompatUI

This change integrates ActivityTransitionAnimator into CompatUI
so the user aspect ratio settings can be launched with the
expand animation.

- Animation invocation
The main logic is implemented in
`CompatUIController#launchUserAspectRatioSettings()`. (The no
animation version is now split out to
`launchUserAspectRatioSettings()`).

- Threading problem (`ActivityTransitionAnimator`)
Just removed the looper check. `mainExecutor` is supposed to
check if resposting to the main thead is needed, so this check
shouldn't be done by the caller. (At least conceptually. We need
to monitor performance regressions in reality.)

- View hierarchy change
Now the settings button has a fullscreen parent which is
requirement for the new animation to work.
`UserAspectRatioSettingsWindowManager` has `mLayoutParent` and
takes care of this new structure. We also need to not let the
fullscreen parent view steal input events by adding only the
button bounds to the touchable region.

- Layout lifecycle change
The layout stays alive until the end of the animation, and needs
to be cleaned up properly. To ensure this, `mIsAnimatingToHide`
is introduced to `UserAspectRatioSettingsWindowManager`, which
blocks all the calls to `release()` during the animation.
Clean-up will be handled in
`DelegateTransitionAnimatorController#onDispose()`.

- Layout bounds calculation change
Layout bounds are calculated in `getWindowLayoutParams()` and
`updateLayoutBounds()`, and this needs to be for the fullscreen
parent view of the button. Also bottom padding needs to be set
to the button.
