Note that this patch also replaces legacy VK_* with KEY_*, and replaces
synthesizeKey() for inputting some characters with sendString() because
it's better and clearer what it does and it sets shiftKey state properly.

We'll stop dispatching keypress events on web contents for conforming to spec of
UI Events. Some existing tests assumes that keypress events are fired even
when non-printable keys are pressed.
This patch makes them check the pref,
"dom.keyboardevent.keypress.dispatch_non_printable_keys_only_system_group_in_content"
and only listen to keydown event instead of keypress even if the pref is true
and expected key event is not a printable key press.
