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.

- * \brief Describes the decoder algorithm interface for algorithm
- *        implementations.
- *
- * This file defines the private structures and data types that are only
- * relevant to implementing an algorithm, as opposed to using it.
- *
- * To create a decoder algorithm class, an interface structure is put
- * into the global namespace:
- *     <pre>
- *     my_codec.c:
- *       vpx_codec_iface_t my_codec = {
- *           "My Codec v1.0",
- *           VPX_CODEC_ALG_ABI_VERSION,
- *           ...
- *       };
- *     </pre>
- *
- * An application instantiates a specific decoder instance by using
- * vpx_codec_init() and a pointer to the algorithm's interface structure:
- *     <pre>
- *     my_app.c:
- *       extern vpx_codec_iface_t my_codec;
- *       {
- *           vpx_codec_ctx_t algo;
- *           res = vpx_codec_init(&algo, &my_codec);
- *       }
- *     </pre>
- *
- * Once initialized, the instance is manged using other functions from
- * the vpx_codec_* family.
