Remove WebM support (and deps libvpx and opus)

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.

-; Instead of doing the transforms stage by stage, it is done by loading
-; some input values and doing as many stages as possible to minimize the
-; storing/loading of intermediate results. To fit within registers, the
-; final coefficients are cut into four blocks:
-; BLOCK A: 16-19,28-31
-; BLOCK B: 20-23,24-27
-; BLOCK C: 8-11,12-15
-; BLOCK D: 0-3,4-7
-; Blocks A and C are straight calculation through the various stages. In
-; block B, further calculations are performed using the results from
-; block A. In block D, further calculations are performed using the results
-; from block C and then the final calculations are done using results from
-; block A and B which have been combined at the end of block B.
