vulkan/wsi/radv: add initial prime support (v1.1)

This is a complete rewrite of my previous rfc patches.

This adds the ability to present to a different GPU that rendering
using a driver side operation that can copy from the tiled to
linear shared image.

This does prime support completely in the swapchain present code,
and each queue has a precreated command buffer for each image
and for the each queue family. This means presenting should work
on graphics and compute queues and transfer in the future.

v1.1: initialise needs_linear_copy in swapchain.
