Cocoa Port: More refactoring work on ClientDisplayView.

- Most notably, HandleGPUFrameEndEvent() now sends the entirety of the
NDSDisplayInfo struct to the client.
- The OpenGL blitter now skips the loading, processing and rendering of
disabled screens.
- Begin preparing DisplayView to handle the upcoming Apple Metal
blitter.
- Do some misc. code cleanup and simplification.
