vulkan/nir: call nir_opt_constant_folding() during vk_spirv_to_nir()

Browse Source 
This prevents bugged CTS tests from tripping over with the following commits.

dEQP-VK.spirv_assembly.instruction.compute.float_controls.fp32.generated_args.denorm_sstep_denorm_flush_to_zero
dEQP-VK.spirv_assembly.instruction.graphics.float_controls.fp32.generated_args.denorm_sstep_denorm_flush_to_zero_*

These tests exhibit undefined values where the result depends on the ordering
of nir_opt_algebraic and nir_opt_constant_folding.
