Fixes link failures when referencing a symbol involving a fingerprint from a different package. Previously we included the `Namespace`'s `import_id` as part of its fingerprint, which caused local and imported namespaces to get different fingerprints. We now store the `import_id` on the `NameScope` instead of on the `Namespace` inst to avoid this problem. Also, when we reach a package-level `NameScopeId`, consistently fingerprint it as a (package name, library name) pair. Previously the fingerprinting depended on whether it was imported or not, as an imported `NameScopeId` had a parent scope (the current package). We need to include the library name here so that private entities with the same name in different libraries have different fingerprints.
