[roll third_party/pigweed] pw_{rpc, sync_stl}: Assert if STL mutex is misused

- Update the pw_sync_stl mutex to track whether it is locked and assert
  if it's used improperly. The C++ standard states that unlocking an
  unlocked mutex is undefined behavior. Neither libc++ nor libstdc++
  crash when a mutex is unlocked multiple times (at least on Linux).
- Annotate the stub pw::rpc::internal::LockGuard class with thread
  safety annotations so that thread safety analysis applies when
  compiling without RPC locking.
