mesa: Remove API facing bits of EXT_paletted_texture and EXT_shared_texture_palette

This was also discussed at XDS 2010.  However, actually making the
change was delayed because several drivers still exposed these
extensions to significant benefit (e.g., tdfx).  Now that those
drivers have been removed, this code can be removed as well.

v2: A lot of bits that were missed in the previous patch have been removed.
