anv: Move nir_lower_wpos_center after dead variable elimination.
When multiple shader stages exist in the same SPIR-V module, we compile
all entry points and their inputs/outputs, then dead code eliminate the
ones not related to the specific entry point later.
nir_lower_wpos_center was being run prior to eliminating those random
other variables, which made it trip up, thinking it found gl_FragCoord
when it actually found something else like gl_PerVertex[3].
Fixes dEQP-VK.spirv_assembly.instruction.graphics.module.same_module.
