dEQP was inadvertendly requiring the presence of these extensions to
even run the tests. There's a WIP fix to the dEQP tests and this CL
implements that fix as a temporary workaround until we can update dEQP.
Fixes several tests in KHR-GLES31.core.constant_expressions and
KHR-GLES31.core.shader_macros. They now correctly return unsupported.
