tsan: switch to the new sanitizer_common mutex
Now that sanitizer_common mutex has feature-parity with tsan mutex,
switch tsan to the sanitizer_common mutex and remove tsan's custom mutex.

sanitizer_common: add new mutex
We currently have 3 different mutexes:
- RWMutex
- BlockingMutex
- __tsan::Mutex
RWMutex and __tsan::Mutex are roughly the same,
except that tsan version supports deadlock detection.
BlockingMutex degrades better under heavy contention
from lots of threads (blocks in OS), but much slower
for light contention and has non-portable performance
and has larger static size and is not reader-writer.
Add a new mutex that combines all advantages of these
mutexes: it's reader-writer, has fast non-contended path,
supports blocking to gracefully degrade under higher contention,
has portable size/performance.
For now it's named Mutex2 for incremental submission. The plan is to:
- land this change
- then move deadlock detection logic from tsan
- then rename it to Mutex and remove tsan Mutex
- then typedef RWMutex/BlockingMutex to this mutex
SpinMutex stays as separate type because it has faster fast path:
1 atomic RMW per lock/unlock as compared to 2 for this mutex.

Semaphore is a portable way to park/unpark threads.
The plan is to use it to implement a portable blocking

to efficiently wait for other things (e.g. we currently
spin to synchronize thread creation and start).
