heap: Ignore TSAN when walking the stack conservatively
Other threads may write the stack of a different thread and use a lock to synchronize such an access. An example for this is interrupt handling. Ignore TSAN for the methods performing the stack walk. There's no need to use relaxed atomic reads as same-thread writes are consistent and for other-thread writes there's no guarantee on what values to observe.
