[attrs] Split off the forced attributes utility into its own pass that
is (by default) run much earlier than FuncitonAttrs proper.
This allows forcing optnone or other widely impactful attributes. It is
also a bit simpler as the force attribute behavior needs no specific
iteration order.
I've added the pass into the default module pass pipeline and LTO pass
pipeline which mirrors where function attrs itself was being run.
