SF: Introduce OutputLayerCompositionState

This moves the display-dependent state from LayerBE.h to a new
OutputLayerCompositionState.h header, adds some simple accessors to
get the new state, and minimally adjusts the existing SurfaceFlinger
code to use the new structure.

Test: atest libsurfaceflinger_unittest libcompositionengine_test
