Generate correct events for extended keys in wxMSW wxUIActionSimulator.

Simulating keys such as WXK_END resulted in WXK_NUMPAD_END event being
generated instead of the expected WXK_END one.

Fix this by returning from wxCharCodeWXToMSW() whether the key code is a
normal or extended one and use this to set KEYEVENTF_EXTENDEDKEY in
wxUIActionSimulator::DoKey().
