i965: Add chipset limits for Haswell GT1/GT2.

The maximum number of URB entries come from the 3DSTATE_URB_VS and
3DSTATE_URB_GS state packet documentation; the thread count information
comes from the 3DSTATE_VS and 3DSTATE_PS state packet documentation.

NOTE: This is a candidate for the 9.0 branch.
