Parse the name of a declaration as a sequence of `NameQualifier`s -- which have a name, possibly parameters, and a trailing period -- followed by a name and possibly parameters. This prepares us for parsing declarations of members of generic classes and similar cases, but actually supporting such member redeclarations is left to a future change. We previously required functions to have parameters, but no longer do, following the direction of #3848. Cases like namespaces that can't actually have parameters are now diagnosed in check instead of in parse. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
