This change makes error messages for parse failures less useful or
completely missing. E.g.:
ffmpeg -f lavfi -i testsrc
Will apply "soon".

For Windows, there's no publicly defined constant for checking for
the i8mm extension yet.

For now, there's not much value in this since Clang don't support
enabling the dotprod or i8mm features with either .arch_extension
or .arch (it has to be enabled by the base arch flags passed to
the compiler). But it may be supported in the future.

Updated to use both the direct HWCAP* macros and HWCAP_CPUID. A
not unreasonably old distribution like Ubuntu 20.04 does have
HWCAP_CPUID but not HWCAP2_I8MM in the distribution provided headers.
Alternatively I guess we could carry our own fallback ha
Set these available if they are available unconditionally for
the compiler.

These are available since ARMv8.4-a and ARMv8.6-a respectively,
but can also be available optionally since ARMv8.2-a.
Check if ".arch armv8.2-a" and ".arch_extension {dotprod,i8mm}" are
supported, and check if the instructions can be assembled.
Current clang versions fail to support the dotprod a

This commit adds VP8 into cbs supported codec list, and enables the
`trace_headers` bitstream filters to support VP8, besides existing AV1,
H.264, H.265 and VP9. It can be useful to debug VP8 stream issues.
Only the READ methods `read_unit` and `split_fragment` are implemented,
