70cebba490 vulkan_encode: Remove unneeded VkImageUsageFlags
There is no point where we need to have the SAMPLED usage on the DPB
resource, and the ENCODE_DST usage does not mean anything.

vulkan: do not reinvent a queue context struct
We recently introduced a public field which was a superset
of the queue context we used to have.

Switch to using it entirely.

This also allows us to get rid of the NIH function which was
valid only for video queues.

vulkan_encode: do not align DPB buffer size
Per subsection B stroke 165 of Chapter 56,
drivers are required to do the aligning, not users.

vulkan: check if current buffer has finished execution before picking another
This saves resources, as dependencies are freed/reclaimed with a lower latency,
and provies a speedup.

vulkan_encode: set the quality level in session parameters
While running this command

./ffmpeg_g -loglevel debug -hwaccel vulkan -init_hw_device vulkan=vk:0,debug=1 -hwaccel_output_format vulkan -i input.y4m -vf 'format=nv12,hwupload' -c:v h264_vulkan -quality 2 output.mp4 -y

It hit this validation error:

Validation Error: [ VUID-vkCmdEncodeVideoKHR-None-08318 ] Object 0: handle =
0x8f000000008f, type = VK_OBJECT_TYPE_VIDEO_SESSION_KHR; Object 1: handle =
0xfd00000000fd, type = VK_OBJECT_TYPE_VIDEO_SESSION_PARAMETERS_KHR;
| MessageID = 0x5dc3dd39
| vkCmdEncodeVideoKHR(): The currently configured encode quality level (2) for
VkVideoSessionKHR 0x8f000000008f[] does not match the encode quality level (0)
VkVideoSessionParametersKHR 0xfd00000000fd[] was created with. The Vulkan spec
states: The bound video session parameters object must have been created with
the currently set video encode quality level for the bound video session at the
time the command is executed on the
device (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdEncodeVideoKHR-None-08318)

This patch adds a new function helper for creating session parameters, which
also sets the quality level and it's called by the H.264 and H.265 Vulkan
encoders.

lavc: add Vulkan video encoding base code
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.
