SF: Predict HWC composition strategy
Asynchronously run ValidateDisplay to determine client composition
strategy. If we can predict that the composition strategy will not
change from frame to frame (for example by looking at whether
the geometry of the layers is changing), the hwc call is run
asynchronously with the gpu composition. If the result of the call is
incorrectly predicted, the gpu composition is rerun.
ValidateDisplay can take multiple milliseconds to complete and by
making it non-blocking in cases where we can predict the strategy
chosen by the hardware, we can jump start the client composition
and shave valuable milliseconds from the frame time.
This feature is disabled by default.
