Skip client composition requests
Keep track of client compositions requests in CompositionEngine and
the buffer used to render the request. If the requests do not change
and the buffer matches, reuse the buffer instead of going
to client composition.
Certain layers properties (buffer format, rounded corner or shadows)
will force the device to go into GPU or mixed composition. In mixed
composition scenarios, we can avoid redundant client composition
requests by reusing the RenderSurface buffers. If the device goes
into GPU composition then all the layers will be composited and there
will be no performance benefit.

Test: dump SurfaceFlinger --timestats -dump
Test: manual testing with mixed and gpu composition scenarios
