layered_dpb only makes sense when dedicated_dpb is set to 1.
For some mysterious reason, some Nvidia drivers stopped indicating
SEPARATE_REFRENCES, but kept the COINCIDE flag, which broke
the code.
The first release of the CTS for AV1 decoding had incorrect
offsets for the OrderHints values.
The CTS will be fixed, and eventually, the drivers will be
updated to the proper spec-conforming behaviour, but we still
need to add a workaround as this will take months.
Only NVIDIA use these values at all, so limit the workaround
to only NVIDIA. Also, other vendors don't tend to provide accurate
CTS information.
There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Only three of the 226 (== AV_CODEC_ID_AV1) entries
have been used. Unsparsing this table is especially
important given that this array lives in .data.rel.ro.

All the fields of FFVkCodecMap are either decoder-only
or encoder-only (with the latter being unused and unset for now).
Yet there is already a per-decoder struct containing
static information about these decoders, namely
VkExtensionProperties.
This commit merges the decoder-parts of FFVkCodecMap
with the VkExtensionProperties into a common structure.
Given that FFVkCodecMap is now unused, it is removed.

ff_vk_codec_map currently is an array indexed by AVCodecID;
it has AV_CODEC_ID_FIRST_AUDIO (= 65536) entries, but uses
only three of them; only 24B of 1MiB were actually used
This commit fixes this by adding an AVCodecID field to the table
and making it non-sparse.

The is coded as 1920x1080, meant to be rendered at 1440x1080 with cropping,
or 1680x1080 before cropping. Currently, the created DPB is 1440x1080, which results
in the image being decoded incorrectly, as the decoder overwrites output memory.
This commit fixes this.
The issue is that we cannot rely on any context existing when we free
frames. The Vulkan functions are loaded in each context separately,
so until now, we've just been loading them on every frame's destruction.
Rather than do this, just save the function pointers we need in each
frame. The function pointers are guaranteed to not change and exist.
All Vulkan HWAccels share the same boilerplate code for creating
session params and this includes a common bug: In case actually
creating the video session parameters fails, the buffer destined
to hold them leaks; in case of HEVC this is also true if
get_data_set_buf() fails.
This commit factors this code out and fixes the leak.

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This commit scraps a bool to signal to recreate the session parameters,
but instead destroys them, forcing them to be recreated.
As this can happen between start_frame and end_frame, do this
at both places.
Move the slice offsets buffer to the thread decode context.
It isn't part of the resources for frame decoding, the driver
has to process and finish with it at submission time.
That way, it doesn't need to be alloc'd + freed on every frame.
This requires using the new AVHWFramesContext.opaque field, as
otherwise, the profile attached to the decoder will be freed
before the frames context, rendering the frames context useless.
Determined experimentally, on various videos and hardware.
On Intel, using less resources in-flight is around 15% faster,
with similar results on Nvidia hardware.

Apparently, the alignment values are informative, rather than mandatory,
but the spec's wording makes it sound as if they're mandatory.
