autotools: Detect SDL_JOYSTICK_MFI for macOS + Weak link with CoreHaptics

Only enable MFI if we also have CoreHaptics to ensure rumble works. See:
 - cmake: Detect SDL_JOYSTICK_MFI for macOS (bc409163a81e5f440399926774202dd2da3e37c3)
 - cmake: Weak link with CoreHaptics (401f485490c68d91b8444f23f61b08e162ef04fb)
