egl: Fix indirect dmabuf importation of none DRM formats

Browse source 
DRM Modifiers are not generically transferrable from a format like NV12 to
their indirect shading format (R8 / RG88). So the helper to this do needs
to be removed from our API.

To make things worse, we support indirect formats that aren't DRM format in
the first place. Notably NV12_16L32 (aka MM21) is not (yet) a DRM format. Yet,
each plane can be indirectly imported using R8/RG88 and a detiling shader.
This patch also removes this constraint restoring zero-copy playback on
Mediatek SoC.

* @plane: the plane in @in_info to create and #GstEGLImage for
* @offset: the byte-offset in the data
*
* Creates an EGL image that imports the dmabuf FD. The dmabuf data
* is passed as RGBA data. Shaders later take this "RGBA" data and
* convert it from its true format (described by in_info) to actual
* RGBA output. For example, with I420, three EGL images are created,
* one for each @plane, each EGL image with a single-channel R format.
* With NV12, two EGL images are created, one with R format, one
* with RG format etc. User can specify the modifier in @in_info_dma
* for non-linear dmabuf.
*
* Returns: (nullable): a #GstEGLImage wrapping @dmabuf or %NULL on failure
