mesa: Remove unnecessary glapitable.h includes.

With 07b85457d9, glapitable.h is included
by core mesa only to know the size of _glapi_table.  It is not necessary
as the same info is given by _gloffset_COUNT.

This change makes _glapi_table opaque to core mesa.  All operations on
it are supposed to go through one of the SET/GET/CALL macros.
