tsan: extend MutexSet to memorize mutex address/stack_id

We currently memorize u64 id + epoch for each mutex.
The new tsan runtime will memorize address + stack_id instead.
But switching to address + stack_id requires new trace,
which in turn requires new MutexSet and some other changes.
Extend MutexSet to support both new and old info to break
the dependency cycles. The plan is to remove the old
info/methods after switching to the new runtime.
