i965: Enable GL_ARB_ES3_1_compatibility on Gen8+ if CS are available.

There are almost no tests in any test suite, but what little I've found
seems to work.  Ilia believes everything is in place.

v2: Predicate the enable on ES 3.1 being available (Gen8+) and also
    ARB_compute_shader being available (requested by Ilia).
