[lld][WebAssembly] Handle weakly referenced symbols when lazy (archive) version is see first
When a weak reference of a lazy symbol occurs we were not correctly
updating the lazy symbol. We need to tag the existing lazy symbol
as weak and, in the case of a function symbol, give it a signature.
Without the signature we can't then create the dummy function which
is needed when an weakly undefined function is called.
We had tests for weakly referenced lazy symbols but we were only
tests in the case where the reference was seen before the lazy
symbol.
