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.

It seems what this function does is a vertical prediction filter, thus
the new name should improve understanding.

Sets the level based on the stream properties if it is not explicitly
set by the user.  Also add a tier option to set general_tier_flag, since
that affects the level choice.

Adds support for determining for level limits, including mapping PTL
blocks to profiles to check profile-dependent level limits.

Set profile compatibility/constraint flags properly (including the
constraint flags used for RExt profiles, as all streams we can currently
generate are RExt-compatible), and use that to add support for the "Main
Intra" and "Main 10 Intra" RExt subprofiles (for which we can re-use the
existing Main and Main10 VAAPI profiles).

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.

Including a unit test.

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.

Also adds greyscale, 4:2:2, 4:4:4 and RGB support.
