Rename the SDL backend to SDL2.

Browse Source 
This distinction is needed because we'll be doing an SDL3 backend in the
future.

/*
This implements a full-featured SDL2 backend. It's intentionally built using the same paradigms as the built-in backends in order to make
it suitable as a solid basis for a custom implementation. The SDL2 backend can be disabled with MA_NO_SDL, exactly like the built-in
it suitable as a solid basis for a custom implementation. The SDL2 backend can be disabled with MA_NO_SDL2, exactly like the built-in
backends. It supports both runtime and compile-time linking and respects the MA_NO_RUNTIME_LINKING option. It also works on Emscripten
which requires the `-s USE_SDL=2` option.
