ogg/vorbis/opus: Make them modules and unbundle thirdparty libs Took the opportunity to undo the Godot changed made to the opus source. The opus module should eventually be built in its own environment to avoid polluting others with too many include dirs and defines. TODO: Fix the platform/ stuff for opus.

Revert "Update opus to 1.3.1 and opusfile to 0.11" This reverts commit e00426c512a7905f5f925d382c443bab7a0ca693. The way we handle platform-specific intrinsics is not good, so the current state will not compile on armv8. This commit also requires SSE4.1 support, which is likely not a good idea for portable binaries. We'll have to redo this with more caution after 3.2 is released, or we might simply drop opus as we're only using it as dependency for theora right now. Fixes #33606.
