Bugfix: Signal thread is not cancelling when f_thread_cancel() is used.

Change the behavior to directly send the terminate signal using `f_thread_signal_write()`.
This appears to get the signal handler thread to terminate when needed.

The simulate validate mode now operates without hanging and without required a terminate signal.
