Vaapi can import external surface, but all the planes of the external frames should be in the same drm object. A new flag is introduced and vulkan can choose to allocate planes in one memory according this flag. This flag will be enabled when the vulkan device is derived from vaapi device, so that this change will not affect current vulkan behaviour.
