AvdanOS New Push A: Vulkan Backend

[Sammy99jsp]

• Synchronise modeset request to change the current framebuffer after the Vulkan queue (rendering the frame) has finished via sync_fd
• Implement pipelining for double-buffered rendering (i.e., render -> render -> show -> render -> show -> render -> show)
• Remove the hard-coded XRGB8888 format and pick the best for the display (HDR ftw!)

This works on my machine ™️ with nvidia_drm, but it'd be nice to test with other graphics cards/integrated too.

i can eventually properly test on all GPUs, intel igpu, intel arc, amd, whatever you need (like next week)
