[scudo] Add thread-safety annotations on TSD data members

Ideally, we want to assert that all the operations on
Cache/QuarantineCache always have the `Mutex` acquired. However,
the current architecture of accessing TSD is not easy to cooperate
with the thread-safety analysis because of pointer aliasing. In
alternative, we add the getters for accessing TSD member and attach
proper thread-safety annotations on them.
