[SF, CE] Rename viewport, frame and destinationClip
This change introduces a new class ProjectionSpace and uses
it in OutputCompositionState to describe the layer stack space,
the physical display space and the oriented display space.
We rename viewport to layerStackSpaceRect, frame to
orientedDisplaySpaceRect and destinationClip displaySpaceRect.
This aims to provide better readibility of the code and
it's also consistent with SurfaceControl.setDisplayProjction
where layerStackRect and displayRect are used for viewport
and frame.
