hidapi: Add SDL_hidapi.c, allows support for multiple hidapi backends.

Browse source 
This is currently supported on Linux and macOS. iOS and Android are not
supported at all, Windows support could be added with some changes to the libusb
backend. The Visual Studio and Xcode projects do not use this feature.

Based on Valve Software's hid.cpp, written in collaboration with Andrew Eikum.

# The hidraw support doesn't catch Xbox, PS4 and Nintendo controllers,

# Except that libusb requires root permissions to open devices, so that's not generally useful, and we'll disable this by default.

# On macOS and Windows, where you don't need libusb or root, we default to yes.
# libusb does not support iOS, so we default to yes on iOS.
