Changes Cocoa references to Quartz and moved funcs into class

Changes references to Cocoa framework in class interface class
names to Quartz such that they match existing Dolphin interfaces.

Additionally, moves the `get_bounds` and `getWindowCenter` helper
functions into the `QuartzInputMouse` class as private methods
as they do not need to be exposed.
