bin: windows: Restore Ctrl-C behavior on windows

[cosmo0920]

After supporting fleet management on Windows,
Ctrl-C events won't be caught up.
This commit re-enables for the behavior.
Windows' ctrl event handlers stolen signals which are overlapped ones. So, we need to handle Ctrl-C events on the newly added event handler for Windows.

In Windows, SIGINT and SIGBREAK are valid ctrl events on their terminal. This is why we only need to handle CTRL_C_EVENT and CTRL_BREAK_EVENT events on console handler.

Closes #7985
