opus/vorbis: Remove dead code not used since 3.0

Browse Source 
Since the new audio system in 3.0 we switched the OGG support to
stb_vorbis, and the Opus stream support was disabled as incompatible
(see #7496).

We still build the libraries as they are needed by the theora and webm
modules, but we don't need any Godot code apart from `register_types`.

Fixes #7496.
