For non-external blit dst buffer, it's bliting the wsi image to a buffer
with mapping populated by vkMapMemory, and it's shared via xcb_put_image
for x11 or memcpy into a shared wl_buffer backed by shm. So we need
additional host stage and host access bit to ensure proper cache flush.
There's no queue family ownership transfer needed.
