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.
