SF: Intro CE::OutputLayer
Introduce compositionengine::OutputLayer, for representing the
composition state of a layer on an output (display)
This change just introduces the OutputLayer class, and modifies
SurfaceFlinger.cpp to create them properly. The new class does not yet
have any state.
Test: atest libsurfaceflinger_unittest libcompositionengine_test
