iris/gfx11+: Request PS payload fields for ALU-based interpolation via 3DSTATE_PS_EXTRA.

Browse Source 
Plumb the prog_data bits recently introduced for ALU-based
interpolation down to 3DSTATE_PS_EXTRA emission in the GL driver, as
well as the uses_depth_w_coefficients bit that was already in use by
the Vulkan driver for CPS shaders.  Even though this is only going to
be used on Xe2+ for now there seems to be no reason not to plumb the
bits on all platforms back to gfx11, since the 3DSTATE_PS_EXTRA
enables already existed on ICL.
