SF: Color changes should dirty entire display
After doing the refactoring of DisplayDevice into
compositionEngine::Output (etc), it became obvious that color matrix and
color mode changes should really be marking the entire output as dirty
so everything is repainted on it.
This patch makes that change, adding tests to verify the intended
behavior.
Test: atest libsurfaceflinger_unittest libcompositionengine_test
