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.
