This patch adds gst_egl_image_from_dmabuf_direct_target_with_dma_drm() and add gst_egl_image_from_dmabuf_with_dma_drm() functions New function gst_egl_image_from_dmabuf_direct_target_with_dma_drm(), where gst_egl_image_from_dmabuf_direct_target() is a specialization of the first. And gst_egl_image_from_dmabuf() is a specialization of new function gst_egl_image_from_dmabuf_with_dma_drm() Co-authored-by: Victor Jaquez <vjaquez@igalia.com> Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4680>
