mesa/formatquery: Added mipmap related <pname> queries

Browse source 
Specifically MIPMAP, MANUAL_GENERATE_MIPMAP and AUTO_GENERATE_MIPMAP <pname>
queries.

From the ARB_internalformat_query2 specification:

   "- MIPMAP: If the resource supports mipmaps, TRUE is returned in <params>.
      If the resource is not supported, or if mipmaps are not supported for
      this type of resource, FALSE is returned.

    - MANUAL_GENERATE_MIPMAP: The support for manually generating mipmaps for
      the resource is returned in <params>.
      Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
      If the resource is not supported, or if the operation is not supported,
      NONE is returned.

    - AUTO_GENERATE_MIPMAP: The support for automatic generation of mipmaps
      for the resource is returned in <params>.
      Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
      If the resource is not supported, or if the operation is not supported,
      NONE is returned."
