pw_watch: Handle EOFError from Ctrl-Z on Windows

On Windows, hitting Ctrl-C can genererate both KeyboardInterrupt and
EOFError due to long-standing Python async problems. This extends the
watcher to gracefully handle this case, avoiding giving the user an ugly
error when quitting in normal watcher operation.

Additionally, this increases the scope of the interrupt handler to also
gracefully exit when hitting Ctrl-C or Ctrl-Z during watcher startup,
when waiting for watchdog to attach all the event handlers.
