a boolean flag. Last advertised and supported modifier currently wins.
The NV12 DRM_FORMAT_LINEAR image should be green in the upper left
corner and white in the lower right.

mesa's freedreno driver supports importing dmabufs with format
DRM_FORMAT_NV12 and DRM_FORMAT_MOD_SAMSUNG_64_32_TILE modifier.
demonstrate weston modifier advertising and import path using this
combination when run with --import-format=NV12.
v2:
- hard code format if platform doesn't implement
EGL_EXT_image_dma_buf_import_modifiers and cannot advertise
format/modifier support.
- squash using valid frame data to fill dmabuf planes
