panfrost: Fake CAPs for dEQP-GLES31

We still have some big ticket items left on GLES 3.0, but it's often
helpful to be able to access higher dEQP levels for debugging features
that just don't quite match a particular API.

Plus, this opens up a whole slew of new features to poke at if boredom
overtakes, ahem.
