source.Identifier previously was used for references and rename, so it needed to take a package policy. Now, it's only used for definition and hover, so it should always be the narrowest package handle. We can use this fact to determine if the identifier is located in its declaring package, and if that package is a test variant, we don't link to the documentation on pkg.go.dev, since it doesn't exist.
