Subject: avcodec/libsvtav1: remove compressed_ten_bit_format and simplify
 alloc_buffer

compressed_ten_bit_format has been deprecated upstream and has no effect
and can be removed. Plus, technically it was never used in the first place
since it would require the app (ffmpeg) to set it and do additional
processing of the input frames.

Also simplify alloc_buffer by removing calculations relating to the
non-existant processing.
