Revert of Update of change event for input type number

Revert of Update of change event for input type number (https://codereview.chromium.org/128133002/)

Reason for revert:
INPUT element dispatches extra events.


Original issue's description:
> Do not dispatch 'change' events during pressing spin buttons for input[type=number].
> 
> TextFieldInputType sends change event for its derived class. Change is
> done for DispatchInputAndChangeEvent to behave similar to
> DispatchChangeEvent.
> DispatchChangeEvent is generated by Range, Radio, File and Checkbox
> input type.
> DispatchInputAndChangeEvent is generated by inputtype for step up and
> down, BaseChooser/BaseMultipleFieldsDateandTime also generates
> DispatchInputAndChangeEvent.
> Since it is different set of inputs that generate DispatchChange and
> DispatchInputAndChange, both are kept but behavior is changed; this
> allows spin button to handle mouseup event.
> Keyboard events are also handled for spin button.
