dri2: add DRI image plane id and offset to base bo.
Add offset argument to createImageFromName2() so that to notify the
driver to wrap the DRM buffer at the specified offset. This is useful
to wrap a DRM buffer describing a YUV picture into several other
images/textures mapping individual Y/U/V components.
Also add a plane id attribute to identify what the DRI image actually
represents. Valid range is 0..2, inclusive.
