Prevent unclean dealloc of SystemState (#33128)

* Prevent unclean dealloc of SystemState

Per current documentation calling Shutdown while any controller is alive is
already prohibited. Also rename the recently-introduced isShutdown method to
isShutDown.

* Add comments and remove the VerifyOrDie()

Upon closer reading Shutdown() was already guaranteed to be called and ensures
that the reference count is 0 at that time, but the documentation was wrong.
