Move the definition into HWC so we aren't dependent on a specific gralloc implementation and so we don't have to create an importer just for different native_handle_t layouts. This will allow supporting multiple gralloc implementations that conform to this layout. For now, this is aligned with gbm_gralloc's struct. Once we change gbm_gralloc and mesa to point to this copy, we can make modifications to the struct.
