retrospectively mark operations @Incubating

New API operations should generally be marked @Incubating,
especially when they occur on prominent interfaces like
Session, Query, or SessionFactory. These ones weren't.
(Sometimes we forget.) And there was a reason they should
have been: their signatures are not type safe, featuring
an unbound type parameter in the return type, even though
their type argument is reified internally. So a
RootGraph<Book> can masquerade as a RootGraph<Author>.
This is a big antipattern that I've been trying to
systematically root out throughout the whole codebase.
