i965/gs: New gs primitive types are supported by HW primitive restart.

When we previously implemented primitive restart, we didn't add cases
to brw_primitive_restart.c's can_cut_index_handle_prims() for the
primitive types that are introduced with geometry shaders.  It turns
out that all of the new primitive types are supported by hardware
primitive restart.
