Subject: [PATCH 1/4] avcodec/libsvtav1: replace vbv_bufsize with
maximum_buffer_size_ms
svt-av1 v1.2.0 has deprecated vbv_bufsize in favor of using
- maximum_buffer_size_ms (--buf-sz)
- starting_buffer_level_ms (--buf-initial-sz)
- optimal_buffer_level_ms (--buf-optimal-sz)
and vbv_bufsize has not been in use since svt-av1 v0.8.6

Subject: [PATCH 2/4] 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.

Subject: [PATCH 4/4] avcodec/libsvtav1: use larger of bit rate and max rate
for buffer size
Generally if maxrate is set, the calculation should be maxrate over
bufsize. This additionally enables CRF + maxrate & bufsize usage.
In order to keep negative values from enabling zero to be treated
as larger and causing a division by zero, check that one of the
variables is larger than zero.
