panfrost: Stub out ES3 caps/callbacks 

Although this is not functional (and the command stream side is not
aiming for ES3 right now), this is enough to run dEQP-GLES3 shader
tests with the version override directive; this is useful, as some ES3
shader feature can occur in ES2 class shaders due to lowering.
