XQuartz: RandR: Refactor legacy mode-switching to be better integrated with RandR 

Adds three new functions
void QuartzRandRSetFakeRootless (void);
void QuartzRandRSetFakeFullscreen (void);
void QuartzRandRToggleFullscreen (void);

The first two are identical to requesting the fake modes from a RandR client
The third responds to cmd-alt-a to leave fullscreen or RandR.
