[C++] Refactor to conform to Google C++ style guide (#5608)

* Automatic refractor of C++ headers to Google C++ style guide

* Automatic refractor of C++ source to Google C++ style guide

* Automatic refractor of C++ tests to Google C++ style guide

* Fixed clang-format issues by running clang-format twice to correct itself. Kotlin was missing clang-format on after turning it off, so it was changed,
