Improved GCController handling on Apple platforms 

Automatically map controllers as gamepads when using the GCController framework and prefer the physicalInputProfile when possible.

Testing with macOS 13.4.1, macOS 14.1.1, iOS 15.7.4, tvOS 17.1:
* iBuffalo Classic USB Gamepad (macOS only)
* Logitech F310 (macOS only)
* Apple TV remote (tvOS only)
* Nimbus MFi controller
* PS4 DualShock controller
* PS5 DualSense controller
* Xbox Series X controller
* Xbox Elite Series 2 controller
* Nintendo Switch Pro controller
* Nintendo Switch Joy-Con controllers
