`lookupVisibleMemberDecls` visits nominal type decls to find visible members of the type. Remembering what decls are visited can be useful information for the clients. * Add a 'VisibleDeclConsumer' callback function that is called when 'lookupVisibleDecls' visits each nominal type decls * Remember the decl names in 'CodeCompletionContext' for future use
