CE: Remove compositionengine::Layer
This was a mostly straightforward refactor that restructures the
interface between SurfaceFlinger and CompositionEngine.
1) Instead of each SurfaceFlinger Layer creating and owning a
compositionengine::Layer, each Layer instead creates and owns a
compositionengine::LayerFECompositionState structure. Containing this
state structure was the only real purpose for
compositionengine::Layer.
2) Use the compositionengine::LayerFE interface in CompositionEngine in
place of compositionengine::Layer. This includes passing a
std::vector for the layers when SurfaceFlinger calls into
CompositionEngine.
3) Alters the LayerFE interface to add the ability to get the state, as
well as changing the existing "latchCompositionState" calls taking a
state reference as the first argument into "prepareCompositionState"
calls that do not need it, as the target of the call owns the state.
4) Alters the SurfaceFlinger Layer implementations to match the LayerFE
interface changes.
