Previously, when InputManagerService requests for PointerController to
change the pointer display, there was no way to know when the request
was completed or whether it succeeded. This could lead to a few issues:
- WM's MousePositionTracker's coordinates would not be updated until the
next mouse event was generated, meaning the position would be out of
sync.
- The creation of a virtual mouse device moves the pointer to a specific
displayId. In order to test this behavior, we would need to sleep in
the test code to wait for the system to update the pointer display and
position, resulting in generally flaky tests.
Here, we add a way to synchonize changes to the pointer display so that
InputMangerService can know the current pointer display with certainty.
PointerController, which is updated in the InputReader thread, is the
source of truth of the pointer display. We add a policy call to notify
IMS when the pointer display changes.
When the pointer display is changed, the cursor position on the updated
display is also updated so that the VirtualMouse#getCursorPosition() API
is synchronized to the pointer display change.

In this CL we introduce SurfaceContorl.getDynamicDisplayInfo
which replaces the current seprate calls for supported and
active display mode, supproted and active color modes and
HDR capabilities.
This way display capabilities can be queried atomically.
Additionally this CL pipes an DisplayMode IDs from
SurfaceFlinger and updates LocalDislayAdapter to use
IDs instead of array indices.

Change-Id: I169e3055d07905e2330e11f158b61ffd366f97e6
Modified current animation logic to use callbacks from the controllers
to further clean and modularize code.

Change-Id: I1073bd78687cca491663c0349751dab4b30aa8e2
Abstracted logic that applies to all pointer types into general
PointerController class and moved implementation of logic specific
to the mouse cursor and touch spots to MouseCursorController and
TouchSpotController, respectively.
