We've had many issues with WebM support and specifically the libvpx library over the years, mostly due to its poor integration in Godot's buildsystem, but without anyone really interested in improving this state. With the new GDExtensions in Godot 4.0, we intend to move video decoding to first-party extensions, and this would likely be done using something like libvlc to expose more codecs. Removing the `webm` module means we can remove libsimplewebm, libvpx and opus, which we were only used for that purpose. Both libvpx and opus were fairly complex pieces of the buildsystem, so this is a nice cleanup. This also removes the compile-time dependency on `yasm`. Fixes lots of compilation or non-working WebM issues which will be linked in the PR.
