Make DataTransferItemList work with plain text entries

https://bugs.webkit.org/show_bug.cgi?id=175596

Reviewed by Wenson Hsieh.

Source/JavaScriptCore:

Added DataTransferItem as a common identifier since it's a runtime enabled feature.

* runtime/CommonIdentifiers.h:

Source/WebCore:

Added the basic machinery to get the list of plain text items to DataTransferItemList and DataTransferItem.

Each DataTransferItem now depends on DataTransfer so it does ref-forwarding like DataTransferItemList to make
DataTransfer alive as long as any DataTransferItem is alive.

Specifications: https://html.spec.whatwg.org/multipage/dnd.html#the-datatransferitem-interface
                https://html.spec.whatwg.org/multipage/dnd.html#the-datatransferitemlist-interface

Tests: editing/pasteboard/datatransfer-items-drop-plaintext-file.html
       editing/pasteboard/datatransfer-items-paste-plaintext.html

* dom/DataTransferItem.cpp:
(WebCore::DataTransferItem::DataTransferItem): Added two variants one for plain text and another one for a file.
(WebCore::DataTransferItem::kind const): Rewritten.
(WebCore::DataTransferItem::getAsString const): Implemented.
(WebCore::DataTransferItem::getAsFile const): Implemented.
* dom/DataTransferItem.h:
(WebCore::DataTransferItem::ref): Added.
(WebCore::DataTransferItem::deref): Added.
(WebCore::DataTransferItem::type const): Returns String instead of AtomicString.
(WebCore::DataTransferItem::kind const): Moved to cpp.
* dom/DataTransferItem.idl: Removed NoInterfaceObject since the interface object should exist on DOMWindow.
* dom/DataTransferItemList.cpp:
(WebCore::DataTransferItemList::length): Implemented.
(WebCore::DataTransferItemList::item): Ditto.
(WebCore::isSupportedType): Added. For now, we only support text/plain.
(WebCore::DataTransferItemList::ensureItems): Added. Constructs the list of DataTransferItems.
* dom/DataTransferItemList.h:
(DataTransferItemList): Added m_items. The list is filled lazily by ensureItems.
* dom/DataTransferItemList.idl: Removed NoInterfaceObject since the interface object should exist on DOMWindow.

LayoutTests:

Rebaselined the tests and added two regression tests for pasting plain text and dropping a plain text file.

Unfortunately, dropping a file is only supported by DumpRenderTree on Mac :( so it's disabled elsewhere.

* editing/pasteboard/datatransfer-idl-expected.txt: Rebaselined now that NoInterfaceObject has been dropped from
DataTransferItem.idl and DataTransferItemList.idl as expected.
* editing/pasteboard/datatransfer-idl.html: Fixed the bug that it wasn't testing IDL for DataTransferItem.
* editing/pasteboard/datatransfer-items-drop-plaintext-file-expected.txt: Added.
* editing/pasteboard/datatransfer-items-drop-plaintext-file.html: Added.

+
+        Added the basic machinery to get the list of plain text items to DataTransferItemList and DataTransferItem.
+
+        Each DataTransferItem now depends on DataTransfer so it does ref-forwarding like DataTransferItemList to make
+        DataTransfer alive as long as any DataTransferItem is alive.

+        * dom/DataTransferItem.cpp:

+        (WebCore::DataTransferItem::deref): Added.
+        (WebCore::DataTransferItem::type const): Returns String instead of AtomicString.
+        (WebCore::DataTransferItem::kind const): Moved to cpp.
+        * dom/DataTransferItem.idl: Removed NoInterfaceObject since the interface object should exist on DOMWindow.
