SurfaceFlingerPerfTests: Scenario builder for SurfaceFlingerPerfTests.

Browse Source 
By exposing a SurfaceControl and allocating a specified number
of buffers to it were now able to test various scenarios
utilizing the SurfaceControl.Transaction apis in
SurfaceFlingerPerfTests.

Test: atest SurfaceFlingerPerfTests
