Support RBM_ZERO_AND_CLEANUP_LOCK in ExtendBufferedRelTo(), add tests For some reason I had not implemented RBM_ZERO_AND_CLEANUP_LOCK support in ExtendBufferedRelTo(), likely thinking it not being reachable. But it is reachable, e.g. when replaying a WAL record for a page in a relation that subsequently is truncated (likely only reachable when doing crash recovery or PITR, not during ongoing streaming replication).
As now all of the RBM_* modes are supported, remove assertions checking mode. As we had no test coverage for this scenario, add a new TAP test. There's plenty more that ought to be tested in this area...
