lima/gp: Clean up lima_program_optimize_vs_nir() a little

Browse Source 
Remove an unnecessary nir_lower_regs_to_ssa as that should be done by
the state tracker, and add a missing DCE pass after running copy
propagation in order to remove the dead copies. This shouldn't fix
anything but the second part will reduce shader sizes.
