[PATCH] Implement windows_nat_target::stop

[Patrick Monnerat <patrick@monnerat.net>]

Insight makes a difference between hitting Ctrl-C (that triggers
target::pass_ctrlc) and clicking the GUI stop button, triggering
target::stop).

As windows_nat did not implement the stop method, the GUI stop button
was inoperant on Windows.
