Currently, several components select atsc_a53, despite
not using anything from it themselves. They only select
it because parsing SEI messages adds an indirect dependency.
But using direct dependencies is more natural, so add
dedicated subsystems for them.
It already allows to remove a superfluous dependency of
the HEVC QSV encoder on hevc_sei and atsc_a53.
Adding new subsystems only becomes effective after a reconfiguration.
In order to force this, some needed headers (which are only included
implicitly before this commit) were included explicitly in
libavformat/allformats.c.

SEI NALUs and several SEI messages are naturally byte-aligned,
so reading them via the bytestream-API is more natural.

VPP in the SDK requires the frame rate to be set to a valid value,
otherwise init will fail, so always set a default framerate when the
input link doesn't have a valid framerate.

This causes the RLE decoder to exit before applying the last RLE run
All images i tested with are unchanged, this makes the special case
for handling the last run unused for non truncated images.

Rather than hard-coding AV_PIX_FMT_VULKAN, expand this to the full list
of formats supported by <libplacebo/utils/libav.h>. We re-use the
existing `format` option to allow selecting specific software formats in
addition to specific vulkan hwframe formats.
Some minor changes are necessary to account for the fact that
`ff_vk_filter_config_output` is now only called optionally, the fact
that the output format must now be parsed before `query_format` gets
called, and the fact that we need to call a different function to
retrieve data from the `pl_frame` in the non-hwaccel case.
