Though these are in essence plain objects that need no refcounting, the presence of a NamedGetter on GleanLabeled means we need to register everything with the wrappercache. Paths not taken: * Making a common utility for Maybe<T> -> dom::Nullable<T> * GleanEvent::Record taking a dictionary instead of object * TimerId as opaque Web IDL * GleanDatetime accept JS Date as well as return it (( Should make decent follow-ups )) Differential Revision: https://phabricator.services.mozilla.com/D186267
