Drop RtAudio driver on Windows

Browse Source 
We've been defaulting to WASAPI since 3.0 and it's superior to RtAudio
in all aspects.

Obsoletes and closes #25503.

Also enable WINMIDI on MinGW, this had been missed initially.

Fix os_windows.cpp and crash_handler_windows.cpp which had weird
dependencies on RtAudio.h's includes (ugh).
