Adds a swapchain create info extension for creating an image using external memory. This removes the need for modifying the image_create_info in the display and wayland backends. There is still code duplication left in these backends though, because swapchain allocation needs to know the selected format. This will be removed when the swapchain images will be created from the swapchain image creator. Moves the definition of drm_format_pair to drm_utils. Removes two step initialization from swapchain_wsi_allocator. Change-Id: I0c937a59cc62e7e3134f0af4728fdda3739237bd Signed-off-by: Iason Paraskevopoulos <iason.paraskevopoulos@arm.com>
