Usually most fields of InputWindowHandle don't change frequently.
Therefore, only the changed instances need to be updated. That
reduces the overhead of JNI invocation (especially
NativeInputWindowHandle::updateInfo which may be called from
setInputWindowInfo).
There should be no behavior change.
- Add a InputWindowHandle.ChangeDetectionWrapper to wrap the original
handle. So the changes of its fields can be tracked.
- Make InputApplicationHandle java side immutable. Its content should
be rarely changed. Then it is easier to compare by instance. This
might also reduces the race condition of accessing its field from
InputDispatcher because the instance is different.
- Move some fields that won't change of InputWindowHandle to the
constructor of WindowState to reduce unnecessary updates.
- When a window cannot receive input, reuse the per-window input
window handle to populate the disabled info, so there won't be a
shared instance that its fields always need to be updated.
- Reduce unnecessary Region#translate if the offsets are zero.
- For a simple activity launch, the invocation amount of
setInputWindowInfo is reduced 90% (from 126 to 11).
- The metrics updateInputWindows_mean of WmPerfTests is reduced 50%+
(from 0.89ms to 0.38ms on an old mid-end device).

The same constant is defined today with slightly different names in both
WindowMananagerService and ActivityTaskManagerService. To prevent
proliferation, make a constant in aidl and use it here.
Also, the two constants used to be in either nanoseconds or
milliseconds.
Make all constants in milliseconds because aidl does not support "const
long", and 5 seconds' worth of nanoseconds does not fit into an int.

ANR - If embedded windows are slow in handling inputs the system should blame the embedded app.
PointerDownOutsideFocus - if a user taps outside the currently focused window onto an
embedded window, treat it as if the host window was tapped.
Rename blessInputSurface -> grantInputChannel and add a name to embedded windows.

First we move it inside of InputWindowInfo instead of InputWindowHandle
so it is part of the data sent across binder. Second we give it a persistent
identity of an IBinder token and use this for comparisons.

The standard SurfaceControl plumbing, plus moving InputWindowInfo from
the services jar to the framework jar so that it is accessible from
SurfaceControl.
