nir: add rcp(w) lowering for gl_FragCoord
On some hardware (e.g. Mali400) the shader needs to apply some
transformations for correct gl_FragCoord handling. The lowering
actions look like the following in pseudocode:
gl_FragCoord.xyz = gl_FragCoord_orig.xyz
gl_FragCoord.w = 1.0 / gl_FragCoord_orig.w
Add this lowering as a nir pass in preparation for using it in the driver.
