When using direct DMABuf upload, supported DRM formats and modifiers pairs should be translated to RGBA. Instead of overwriting the translation to RGBA, which may endup having nothing to override, we introduce a new flag for the transform helper, so it can do direct translation. This fixes a regression introduced by !9306, and fixes more negotiations issues. Fixes #4525 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/9339>
