Do you need this block of change? Looks like UpdateTextInputState() is called
with |send_ime_ack| == false for aura.

An alternate to this would be to always set |send_ime_ack| to false towards the
beginning of this function.

Conditional compilation required for IncrementOutstandingImeEventAcks since it
is only defined for Android.  Moved the Aura logic as suggested.

     Send(new ViewHostMsg_TextInputStateChanged(routing_id(), p));
 
     text_input_info_ = new_info;
