include: update GLES gl2ext header to no longer reference bad function

There was a previous error in the gl.xml and generated files that
referenced glMultiDrawElementsBaseVertexOES. This function should not
exist, only the EXT-suffixed version should.

Leaving the other headers alone to avoid conflicts with GL 4.6 work.
