panfrost: Enable NV_primitive_restart on Valhall

Browse source 
Unlike literally every other mesa/st emulation, for some inexplicable reason we
need to pretend to support the CAP and then set a different EMULATE cap instead
of the emulation keying off the lack of support for the CAP. Set the CAPs
accordingly so we get NV_primitive_restart (with emulation of non-fixed
indices).

This gets Mesa to advertise GL 3.1 on Mali-G57 as intended.
