perf(semantic): reduce memory copies (#4216) Reduce memory copies when resolving references in `Semantic`. If parent scope has no unresolved references for `name`, there is no need to generate a new `Vec<ReferenceId>` for `name` and copy in contents from current scope. Just move the existing `Vec` to the parent.
