Cherry-pick: ICU-20520, ICU-20570, ICU-20595, ICU-20588 UMutex refactoring
Thic CL cherry picks four commits from upstream that refactor UMutex and
introduce thread-safety improvements:
1. ICU-20520 UMutex refactoring
- Use STATIC_NEW for mutex creation, to avoid order-of-destruction problems
by avoiding destruction altogether, while avoiding memory leak reports.
- Remove UConditionVar, replace with direct use of std::condition_variable
https://github.com/unicode-org/icu/commit/b772241b52fcec07b1909d44d156fbcd0cbfb20c
2 .ICU-20570 UInitOnce instances, add explicit initialization where it was missing.
https://github.com/unicode-org/icu/commit/a97cfb01b917125fdb9705cf79786188cebb6e2e
3. ICU-20595 Make icu::TimeZone::AdoptDefault thread safe
correct the mutex
Remove comments about not thread safe
https://github.com/unicode-org/icu/commit/cb40d8b1a5eb6dd01e3972db5e1a05b672202f80
4. ICU-20588 UMutex, add cleanup of underlying mutexes, and simplify usage model
