Generalized the idea of joystick driver priority

Browse Source 
Joystick drivers are sorted by priority in the driver list, and higher priority drivers report whether they are handling a device when lower priority drivers want to add it to their device list.

This has been handled ad-hoc with the Windows and HIDAPI drivers, but this formalizes the idea and makes sure that GameInput has the highest priority of the Windows drivers.
