Currently EditableInputConnection#requestUpdateCursorAnchorInfo
never returns false unless InputMethodManager is somehow
unavailable.
This is problematic, especifially when we add a new flag to
EditableInputConnection#requestUpdateCursorAnchorInfo in a
future release.
With this CL, #requestUpdateCursorAnchorInfo does nothing and
immediately returns false when one ore more unknown bits are
specified.
