gallium: Add a pipe cap for whether primitive restart works for patches.
Some hardware supports primitive restart on patch primitives, and other hardware does not. Modern GL and ES include a query for this feature; adding a capability bit will allow us to answer it. As far as I know, AMD hardware does not support this feature, while NVIDIA and Intel hardware does. However, most Gallium drivers do not appear to support tessellation shaders yet. So, I've enabled it for nvc0 and disabled it everywhere else.
