…guration Fixes cockroachdb#111409. Fixes cockroachdb#111492. This commit updates addLockTableSpans to account for the way that shared locking requests declare their latches. Even though they declare a "read" latch, they do so at max timestamp, which gives them sufficient isolation to write to the lock table without having to declare a write latch and be serialized with other shared lock acquisitions. Release note: None
