Don't use std::unique_lock unless we have to 
Replace where possible by std::lock_guard which is more light-weight.

Cosmetics: Pass patterns around as std::string_view instead of StringRef 
- The patterns are not used in hashing, there should not be a performance
  impact when we use stuff from the standard library instead.

- added forgotten .reserve() in FunctionsMultiStringPosition.h

Support for Clang Thread Safety Analysis (TSA) 
- TSA is a static analyzer build by Google which finds race conditions
  and deadlocks at compile time.

- It works by associating a shared member variable with a
  synchronization primitive that protects it. The compiler can then
  check at each access if proper locking happened before. A good
  introduction are [0] and [1].

- TSA requires some help by the programmer via annotations. Luckily,
  LLVM's libcxx already has annotations for std::mutex, std::lock_guard,
  std::shared_mutex and std::scoped_lock. This commit enables them
  (--> contrib/libcxx-cmake/CMakeLists.txt).

- Further, this commit adds convenience macros for the low-level
  annotations for use in ClickHouse (--> base/defines.h). For
  demonstration, they are leveraged in a few places.

- As we compile with "-Wall -Wextra -Weverything", the required compiler
  flag "-Wthread-safety-analysis" was already enabled. Negative checks
  are an experimental feature of TSA and disabled
  (--> cmake/warnings.cmake). Compile times did not increase noticeably.

- TSA is used in a few places with simple locking. I tried TSA also
  where locking is more complex. The problem was usually that it is
  unclear which data is protected by which lock :-(. But there was
  definitely some weird code where locking looked broken. So there is
  some potential to find bugs.

*** Limitations of TSA besides the ones listed in [1]:

- The programmer needs to know which lock protects which piece of shared
  data. This is not always easy for large classes.

- Two synchronization primitives used in ClickHouse are not annotated in
  libcxx:
  (1) std::unique_lock: A releaseable lock handle often together with
      std::condition_variable, e.g. in solve producer-consumer problems.
  (2) std::recursive_mutex: A re-entrant mutex variant. Its usage can be
      considered a design flaw + typically it is slower than a standard
      mutex. In this commit, one std::recursive_mutex was converted to
      std::mutex and annotated with TSA.

- For free-standing functions (e.g. helper functions) which are passed
  shared data members, it can be tricky to specify the associated lock.
  This is because the annotations use the normal C++ rules for symbol
  resolution.

- input_format_parallel_parsing=true
- write_progress_on_update=true

It is possible concurrent access to the following:
- writeProgress() (class properties) (guarded with progress_mutex)
- thread_data/host_cpu_usage (guarded with profile_events_mutex)
