Mock static initialization order 09

cpp static order initialization is not guarantee.
In order to avoid the mess, we need to have a lazy init schema.
Replacing all mock_bt extern with the correct header
```
's|extern std::map<std::string, int> mock_function_count_map;|#include "test/common/mock_functions.h"|'
```
