mpv: Move all wrappings to a single wrapper Nix function
Inspired by `wrapNeovim`, write a wrapMpv Nix function that creates a derivation that has all of the environment that was added if needed at the unwrapped version. Add derivations to all-packages.nix in an almost compatible way and make `mpv-with-scripts` throw a message implying to switch to `wrapMpv` which has an incompatible signature. Add to vapoursynth a new passthru attribute `python3` that is used in passed down to the wrapper to ensure ABI compatibility with `PYTHONPATH`.
