nir/lower_wpos_center: support adding sample position to fragment coordinate
According to section 14.6 of the Vulkan specification:
"When sample shading is enabled, the x and y components of FragCoord
reflect the location of the sample corresponding to the shader
invocation."
So add a boolean parameter to the lowering pass to select this behavior
when we need it.
