qapi/introspect.py: Type _gen_tree variants as Sequence[str]
Optional[List] is clunky; an empty sequence can more elegantly convey "no variants". By downgrading "List" to "Sequence", we can also accept tuples; this is useful for the empty tuple specifically, which we may use as a default parameter because it is immutable.
