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.
Set the minimum version to 0.35.0 (libva 1.3.0) and remove redundant
configure tests. This also allows the proprietary libmfx fork of libva,
which always shows the version number 0.99.0 (independent of the actual
version).

This checks the value exactly for intra frames and checks it against a
minimum for inter frames as they can be variable.

MSVC expands the preprocessor directives differently, making the
version check fail in the previous form.
Clang can warn about this with -Wexpansion-to-defined (not currently
enabled by default):

The libaom doxy says that a value of 0 for the threads fields is
equivalent to a value of 1, whereas for avctx->thread_count it means
the maximum amount of threads possible for the host system.
Use av_cpu_count() to get the correct thread count when auto threads
is requested.
