Add WebKit2 API to figure out if an input or textarea was edited

https://bugs.webkit.org/show_bug.cgi?id=56474

Reviewed by Adam Roben.

Source/WebCore: 

Add HTMLInputElement::lastChangeWasUserEdit and HTMLTextAreaElement::lastChangeWasUserEdit
and use them to implement -[DOMHTMLInputElement _isEdited] and -[DOMHTMLTextAreaElement _isEdited]
as well as API in WebKit2.

* WebCore.exp.in:
* bindings/objc/DOMHTML.mm:
(-[DOMHTMLInputElement _isEdited]):
(-[DOMHTMLTextAreaElement _isEdited]):
* html/HTMLInputElement.cpp:
(WebCore::HTMLInputElement::lastChangeWasUserEdit):
* html/HTMLInputElement.h:
* html/HTMLTextAreaElement.cpp:
(WebCore::HTMLTextAreaElement::lastChangeWasUserEdit):
* html/HTMLTextAreaElement.h:

Source/WebKit2: 

Expose WKBundleNodeHandleGetHTMLInputElementLastChangeWasUserEdit and
WKBundleNodeHandleGetHTMLTextAreaElementLastChangeWasUserEdit. Next time,
I will work on giving these functions longer names.

* WebProcess/InjectedBundle/API/c/WKBundleNodeHandle.cpp:
