CHANGE(client): Drop support for all legacy codecs

Opus has been the go-to codec for years now and there is absolutely no
reason why one would want to use any of the legacy codecs (Speex or
CELT) its stead.

Thus, this commit completely removes the support for these codecs from
the Mumble client.

Incidentally, having different codecs available somehow even caused some
audio artifacts, which should now be resolved as well.

Fixes #4538
