UUIDs do not have to be unique if their type sets them apart, so avoid using
AnyType, since we are only interested in specific types.

There is no MMX DSP code for VVC, so one can use the stricter
declare_func which also tests that we are not in MMX mode
at the end of this function.

Otherwise vvc_intra.o gets pulled in by the vvc_mc checkasm
test and it in turn pulls vvc_ctu.o and then the rest of vvcdec
and lavc in. Besides being bad size-wise this also has the downside
that it pulls in avpriv_(cga|vga16)_font from libavutil which are
marked as being imported from another library when building
libavcodec as a DLL and this breaks checkasm because it links
both lavc and lavu statically.

This BSF is supposed to be used in conjunction with mp3_header_compress,
which has been removed more than ten years ago in commit
c6080d8900. It mangled the headers
by removing the CRC field as well as fields that are supposed
to stay constant for the entirety of a stream (which are put into
extradata). This made these files unplayable; they need to be
decompressed with the BSF first (which does not happen automatically).
Even in this case the CRC does not get restored.
I am not aware that such compressed files exist at all; therefore
this commit removes the BSF completely.

This is possible because the lifetime of both coincide.
Besides reducing the number of allocations this also simplifies
access to VulkanFramesPriv as one no longer has to
go through AVHWFramesInternal.

Use AVHWFramesContext.hwctx instead.
This simplifies accesses to VDPAUFramesContext as one no longer has
to go through AVHWFramesInternal.

Correct the names of the format-specific headers (not hwframe_*.h)
and clarify that the user shall ignore this field if there is no
public context associated with it.
In particular, this allows to use this field for the private context
alone if there is no public context. This can't break conforming
API users, because they always have to live with the possibility
that a new public context has been introduced.

Without ff_vk_exec_discard_deps which is called by ff_vk_exec_wait,
the reference count of hwframe context cannot reach zero due to
circular reference created by ff_vk_exec_add_dep_frame.

It was always intended that the buffers returned by
RefStruct shall have the same alignment guarantees
as the buffers returned by av_malloc(); said alignment
depends upon the arch and the enabled instruction set
and the code used STRIDE_ALIGN as a proxy for this.
Yet since 7945d30e91
there is a better way to get av_malloc's alignment:
ALIGN_64 in mem_internal.h. So use this.
