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. Reviewed-by: Jason Ekstrand <[email protected]>
