switch the windows build from 32 bit to 64 bit

- update CI to build with MSYS2/autotools and the FPC cross toolchain
- fetch the x86_64 DLL bundle and download bass.dll separately
- enable the OpenCV wrapper on Windows and link it as a DLL there
- update bundled library names and versions for projectM, portaudio and freetype
- remove obsolete 32 bit runtime DLLs from the repository
