anv: implement EDS2.extendedDynamicState2PatchControlPoints

Browse Source 
We make the compiler assume the worst possible case (it's not great
because we have to burn 32 GRFs of potential input data) and then we
push the actual value through push constants.

This enables VK_EXT_gpl usage on zink, which causes two traces to change
their results.  Raven is an imperceptible change, blender has missing
original pngs but looks plausible.
