No-op refactor to make Environment#getGlobalDeclaration() take a NonLocalBinding instead of just a name. The idea is that in subsequent PRs we can use information about the binding to resolve a type more accurately. For example, we can resolve Array differently if its an import or local and not the global Array. Similar for resolving local useState differently than the one from React.
