mesa/es3.1: Enable ES 3.1 API and shading language version

This is a bit of a hack for now.  Several of the extensions required for
OpenGL ES 3.1 have no support, at all, in Mesa.  However, with this
patch and a patch to allow MESA_GL_VERSION_OVERRIDE to work with ES
contexts, people can begin testing the ES "version" of the functionality
that is supported.
