Rather than just adding `Self` to the lexical scope, add it to the class's name scope so that it is visible in later lexical scopes for the same class -- in particular, for out-of-line definitions of members. Also switch some tests in `check/testdata/class` over to making idiomatic use of `Self` both inside a class and out-of-line, now that it works more consistently. Note that this does not permit using `Class.Self`, but only because we don't yet support keyword names after `.` at all. If that changed, one could use `Class.Self` to redundantly refer to `Class`. Whether we allow that is left to a future decision.
