Collect built-in LWLock tranche names statically, not dynamically. There is little point in using the LWLockRegisterTranche mechanism for built-in tranche names. It wastes cycles, it creates opportunities for bugs (since failing to register a tranche name is a very hard-to-detect problem), and the lack of any centralized list of names encourages sloppy nonconformity in name choices. Moreover, since we have a centralized list of the tranches anyway in enum BuiltinTrancheIds, we're certainly not buying any flexibility in return for these disadvantages.
Hence, nuke all the backend-internal LWLockRegisterTranche calls, and instead provide a const array of the builtin tranche names. (I have in mind to change a bunch of these names shortly, but this patch is just about getting them into one place.)
