This commit adds the first Vulkan hardware encoder.
Currently, P, and **B**-frames are supported. This marks the
first implementation to support both.
The encoder has feature-parity with VAAPI.

This commit adds the common Vulkan video encoding framework.
It makes full use of the asynchronous features of our new common
hardware encoding code, and of Vulkan.
The code is able to handle anything from H264 to AV1 and MJPEG.

The old query code never worked properly, and did some hideous
heuristics to read the status bit, and work that into a return
code.
This is all best left to callers to do, which simplifies
our code a lot.
This also fixes minor validation errors regarding calling queries
which are not in their acti
Both of these are fundamentally incompatible with video decoding.

This solves the issue of an av_log function being called

The issue is that we ask for storage images by default if
available, but because that is gated by the format supporting
storage images, and the check for the format supporting storage
images is gated by the usage, this resulted in a catch-22.

This caused images to be created without a storage usage, which broke
at least lavapipe.

Vulkan supports some stupidly odd hardware, that unfortunately,
most modern GPUs happen to be.
The DPB images for encoders may be required to be preallocated
all at once, and rather than be individual frames, be layers of
a single frame.
As the hw_base_encode code is written with the thought that
Vulkan requires this, as it needs to initialize state upfront.

Millions of hours of CPU-time are probably wasted to reencode
already-perfectly-encoded content, just for cutting ;)
