avcodec/codec_desc: make LCEVC a video media type

Browse Source 
Every container signals it as such, and the data media stream type is too
undefined and unsupported across the codebase that even if no standalone
decoder can be present for it, it's preferable to it.

This is technically an API break, but LCEVC support has been minimal until
now so it should be safe.
