Vulkan blit
This is part of the gsoc project Videoconvert for PipeWire.
The purpose of this MR is to track the progress and be a base for discussions and therefore will contain a lot of experimental changes and hacks.
Replace the fancy compute shader with a simple blit. This should let us work on enabling support for formats from the rgb(a) family.
