avformat/ivfenc: fix writing codec tag
The value in AVCodecParameters->codec_tag may not be correct for IVF,
as it's the case when remuxing AV1 streams from mp4, so ignore it and
write the correct value based on codec ID instead.

Also bump the API version requirement to 10.9.5, because on olders versions

Set profile compatibility/constraint flags properly (including the

existing Main and Main10 VAAPI profiles).

cbs_h264: Fix default value for max mv lengths
A recent version of the standard changed the max and default to 15, from
16 in older versions. This updates the default to 15 to match, but the
max stays as 16 so that we don't reject older streams.

hwcontext_vaapi: Improve format mapping
Give the entries in the VAAPI format map table an explicit type and add
functions to do the necessary lookups. Add another field to this table
indicating whether the chroma planes are swapped (as in YV12), and use
that rather than explicit comparisons where swapping is needed.

hwcontext_vaapi: Improve logging around quirk detection
Clarify that the list is the naughty list, and therefore being on it is

changed).

vaapi_encode_h264: Properly set constraint flags
constraint_set1_flag should be set for constrained baseline and main
profiles, because the stream conforms to main profile.
constraint_set3_flag should be set for high profile when the stream
is intra-only.
constraint_set4_flag should always be set for main and high profiles
because interlaced encoding is not supported.
constraint_set5_flag should be set for main and high profiles when
B-frames are not used.
Also fix the setting of max_num_ref_frames - use the gop_size value
to check for intra-only rather than the constraint flag (which is not
necessarily set).

The codec sequence headers may contain fields which can overwrite the
fine parameters given in the specific settings (e.g. a crude bitrate

VAEncMiscParameterRateControl). Always reapply all global parameters
after a sequence header to avoid this causing problems.

vaapi_encode: Choose profiles dynamically
Previously there was one fixed choice for each codec (e.g. H.265 -> Main
profile), and using anything else then required an explicit option from
the user. This changes to selecting the profile based on the input format
and the set of profiles actually supported by the driver (e.g. P010 input
will choose Main 10 profile for H.265 if the driver supports it).
The entrypoint and render target format are also chosen dynamically in the
same way, removing those explicit selections from the per-codec code.
