Added some convenience API for platform input contexts

QPlatformInputContext now gets notified on changed focus and
has inputMethodAccepted() telling whether current focus object
accepts input method events.

Also adapted IBus plugin to use this. Key event filtering for
focused objects without input method support got fixed by the
change.
