fix(high contrast text): fix highlight/selection is obscured by high contrast text background rectangle

Since high contrast text draws a solid rectangle background behind the
text, it covers up the highlights and selections. In this case we draw
over the top of the text with a blend mode that ensures the text stays
high-contrast.

Updates the drag zone indicators to Regions based on the task's pre-drag
windowing mode. Drag zone targets for freeform tasks have been updated
while other windowing modes remain the same.

Also, changes the coordinates fetched in handleCaptionThroughStatusBar
to raw x/y coordinates. This is due to each split stage having its own
coordinate space. Split left/right indicators from a drag from
splitscreen would not work properly otherwise.

Note these are visually inaccurate; transitions will be tied to these
regions in a future CL.

Adds flicker test for the CUJ with entering pip with source rect hint.
This specifically tests with auto enter enabled, but we can probably
add a separate case for entering manually. The test uses a rectangle
as the source rect, and there is a jump at the end of the transition
as the app doesn't update the layout for pip, but this is more of an
app issue and doesn't affect the test case.

Implement auto-enter PiP in PiP2 while in gesture
navigation mode.
Launcher handles the animation as a part of the first
TO_FRONT transition (no changes there).
For now only startSwipePipToHome() and stopSwipePipToHome()
IPC calls are set up to let launcher start PiP animation.
The plan is to add the pip animation listener to properly
update Launcher state in [2/N] CL of this series (similar to pip1).

This is followed by a call to requestStartTransition()
-> PipTransition#handleRequest() for TRANSIT_PIP type of a transition.

The flow here overlaps with other enter PiP2 flows, as we use
WindowContainerTransaction#movePipActivityToPinnedRootTask()
to update the WM state with the new bounds (unlike in PiP1).

Then, we recognize that this is a swipe PiP to Home animation
in PipTransition#startAnimation() and we carry out a no-op animation
essentially finishing TRANSIT_PIP. The plan is to continue overlay
animation here as well in later CLs of this series. So overlay is
not animating properly for now - hence testing would require non-null
srcRechHint in PictureInPictureParams.

In some close to square displays, status bar and cutout have been
decoupled from the configuration. Only navigation bar/taskbar insets are
considered in resolving fixed orientation configurations.

With taskbar insets, the aspect ratio of the containingAppBounds in
these displays can be <= activity aspect ratio, even if the orientation
is not respected with insets e.g. portrait app in portrait display
(which is landscape with taskbar insets). Don't letterbox the activity
in this case if the resulting fixed orientation bounds still matches the
parent bounds.

Don't show the aspect ratio button if the letterboxed activity is only
minimally letterboxed (activity bounds are more or equal to stable
bounds).

getExpandedViewContainerPadding already accounts for the insets when
calculating the padding around the bubble expanded view.

mPositionRect is the rect that accounts for the insets, so when
using it in combo with getExpandedViewContainerPadding, we'd subtract
any insets twice. mScreenRect does not account for the insets, so
we should use that here instead.

Beforehand the state was using fixed size, which could be below minimum
size for a given screen size, e.g. after you fold/unfold the device.

This change makes it so that the bounds scale is used instead of size,
which makes the PiP size always align with PiP Size Spec after reentry.

Use system perf hints during PiP
interactions to avoid animations at low refresh rates.

The latest patchset introduces a new wrapper around
HighPerfSession to make session management safer and easier
for PiP component.

Namely, we introduce the following two helper classes:

 - PipPerfHintController:

	A wrapper around SystemPerfHintController to start sessions
	with an interface allowing registering optional timeouts with
	timeout callbacks.

	This should act as a safeguard, especially for complex interactions.
	For now this safeguard is only used for logging as a preventative
	measure against introducing any regressions to avoid
	"high performance hint starvation".

 - PipPerfHintController.PipHighPerfSession:

	A wrapper around HighPerfSession that helps keep track of
	active sessions present.
	PipHighPerfSession also makes sure necessary updates are made
	to cleanup if the session is either closed directly or
	if it is garbage collected.

	For example, if the session client loses all strong references
	to the session returned by PipPerfHintController#startSession(),
	the GC reclaims the memory, and we close the session internally.
	Moreover, an internal WeakHashMap is updated to avoid calling
	timeout callback if one was registered
	(these callbacks pass in a reference to the session,
	in case a client uses multiple).

As a side note, manual testing has shown so far that all PiP transition
animations are by default at maximum refresh rate of 120Hz; hence, this CL only
addresses non-Transitions related PiP CUJs, like double taps,
pinch-to-resize, drags, stashes and unstashes.

- It's sent from PipTransitionController when we start and finish the
  animation
- Removed the restriction that onPictureInPictureUiStateChanged can only
  be sent to a pinned task, since this entering PiP callback would be
  received when the task is still in full-screen

Note that there is no isExitingPip API being added here since
- apps normally do not restore overlays such as video controls when
  exiting from PiP
- if apps do want to restore the overlays, it maybe preferred to do that
  in onPictureInPictureModeChanged(isInPictureInPictureMode=false)
  callback rather than the beginning of exit PiP animation
