gl/egl: Add gst_egl_image_from_dmabuf_direct() function
The colorspace conversion happens during the upload so the necessary hints
must be provided to ensure that the conversion works correctly.
At least the Mesa Intel driver will create a texture without error but
produces an incorrect result. Use eglQueryDmaBufModifiersEXT() to check if
non-external upload is supported for the given format.
Based on a patch from Carlos Rafael Giani <dv at pseudoterminal.org>.
