[Forms] Move wheel event handler to spin button class

• Component: Forms
• Status: RESOLVED FIXED

In current implementation, wheel event handler is implemented in TextFieldInputType and called from NumberInputType and BaseDateTimeInputType class.

To shared wheel event handler code within them and multiple field time UI, I would like to move implementation of wheel event handler into SpinButton class.

You wanted to remove HTMLInputElement dependency from SpinButtonElement, right?

Yes, I really want to do so. 
I would like to make this patch to be handling wheel event only.

I'll free SpinButtonElement ffrom HTMLInputElement dependency in other patches like:

Patch 1. Do svn copy TextControllInnerElements.{cpp,h} to SpinButtonElement.{cpp,h}
Patch 2. Rename SpinButtonActionHandler to SpinButtonElementOwner with willHandleStepAction()
