In the case of encoders and filters when importing a DMABuf, use GstVideoInfoDmaDrm to get the drm fourcc and modifier. In both cases, instead of keeping the original GstVideoInfoDmaDrm from caps, the GstVideoInfo part of the structure is converted as canonical one, given the format from the fourcc. It's kept in the way to handle V4L2 linear DMABufs and to avoid too many changes in the current code. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5264>
