Provide a way to predefine LWLock tranche IDs. It's a bit cumbersome to use LWLockNewTrancheId(), because the returned value needs to be shared between backends so that each backend can call LWLockRegisterTranche() with the correct ID. So, for built-in tranches, use a hard-coded value instead.
This is motivated by an upcoming patch adding further built-in tranches.
