radv: generate same device UUID as radeonsi
This is required for interop use cases. The same device must report identical UUIDs through the GL and Vulkan APIs so that users can identify when it is safe to perform a memory object import. v2: use ac helpers to calculate the uuid Signed-off-by: Andres Rodriguez <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
