obs-vst: Remove submodule in favour of direct merge 2/2

Please visit the submodule repo for blame history:
https://github.com/obsproject/obs-vst

This also replaces the obs-vst .clang-format with obs-studio's.

This commit depends on the previous commit, which removes the submodule
separately as Git complains otherwise.
