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.

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.

libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags
as well as the definition of AVCodecHWConfigInternal and some
macros to create them.
The users of these two are nearly disjoint: The flags are used
by files providing AVHWAccels whereas AVCodecHWConfigInternal
is used by files providing codecs (for FFCodec.hw_configs).
This patch therefore moves these flags to a new file hwaccel_internal.h.

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.
