Nikolaj Bjorner 62b530e945 Fix SIGINT handler to use sigaction with SA_ONSTACK flag 
Related to #7305

Update SIGINT signal handler to use `sigaction` with `SA_ONSTACK` flag.

* Replace `signal` function with `sigaction` function in `src/util/scoped_ctrl_c.cpp` to register the SIGINT handler.
* Set the `SA_ONSTACK` flag for the SIGINT signal handler in `src/util/scoped_ctrl_c.cpp`.
* Update `on_ctrl_c` function to use `sigaction` in `src/util/scoped_ctrl_c.cpp`.
* Modify `scoped_ctrl_c` struct in `src/util/scoped_ctrl_c.h` to include `struct sigaction m_old_action` instead of `void (STD_CALL *m_old_handler)(int)`.
