juliac: add invokelatest_gr override to juliac-buildscript.jl (#57205)

This extends the existing `invokelatest` hack to treat the current world
as the latest world for globalref lookups.

Since this came up, @Keno can you confirm that any world-age-affecting
operations on bindings still require `eval()`?
Are there any imports / assignments / etc. that might bump the world age
by changing a binding?
