Inline IMM.DelegateImpl#finishInput()

This CL inlines

  InputMethodManager.DelegateImpl#finishInput().

There must be no observable behavior change except for we no longer
log IME tracing event

  "InputMethodManager.DelegateImpl#finishInput".

If that event is turned out to be useful, we can add a similar tag
later, but for now it doesn't look to be critically useful.
