FYI it's not recommended to overload functions in Chromium. It could also be
confusing to the reader when they read both SendKeyEvent(int, int, int) and
SendKeyEvent(int, int) and had hard time realizing the difference between native
keycode and usb keycode O_o

Not sure what's the best name though. SendKeyEventWithUsbkeycode?
