When a critical section completes with leftover waiters, they are reparented such that the waiters are now waiting on the parent scope. Before this commit, this did not correctly update the `gate` reference in the waiter. This commit also fixes 2 other reparenting bugs, and adds additional test coverage for reparenting: * Ensures that reparenting works with multiple layers of nested critical sections, by skipping already reparented critical sections in the family hierarchy. * Fixes bug when reparenting waiters for nested critical sections, where they were being removed from the incorrect list.
