This is the second part for loading the library at runtime, changes
compared to previous patch revisions:

-No atexit anymore
-No global states anymore
-Moved the registry read for Windows from a separate function inside the
function to load the dynamic library and simplified it, reducing the
amount windows-specific code.

Tested with 2 VapourSynth inputs on these platforms, no problems and
clean exit:

-Linux x86_64 (Ubuntu 22.04)
-Windows 10 x86_64
-macOS 14 aarch64

Best regards
Stefan
