Fully outline all GlobalRefs (JuliaLang#56746)

This is an alternative to JuliaLang#56714 that goes in the opposite direction -
just outline all GlobalRefs during lowering. It is a lot simpler that
JuliaLang#56714 at the cost of some size increase. Numbers:

I don't have numbers of JuliaLang#56714, because it's not fully complete.
Additionally, it's possible that restricting GlobalRefs from arguments
position would let us use a more efficient encoding in the future.
