[GTK] Move GtkDragAndDropHelper from Platform to WebKit2
https://bugs.webkit.org/show_bug.cgi?id=137422

Reviewed by Martin Robinson.

Source/WebCore:

Remove ClipboardUtilitiesGtk and GtkDragAndDropHelper.

* PlatformGTK.cmake:
* platform/gtk/ClipboardUtilitiesGtk.cpp: Removed.
* platform/gtk/ClipboardUtilitiesGtk.h: Removed.
* platform/gtk/GtkDragAndDropHelper.cpp: Removed.
* platform/gtk/GtkDragAndDropHelper.h: Removed.

Source/WebKit2:

WebKitWebViewBase is currently the only user of
GtkDragAndDropHelper, that was added to share the code with
WebKit1. Move all the drag and drop logic to a new class
DragAndDropHandler.

* PlatformGTK.cmake: Add new files to compilation.
* UIProcess/API/gtk/PageClientImpl.cpp:
(WebKit::PageClientImpl::startDrag):
* UIProcess/API/gtk/WebKitWebViewBase.cpp:
(webkitWebViewBaseConstructed):
(webkitWebViewBaseDragDataGet):
(webkitWebViewBaseDragEnd):

(webkitWebViewBaseDragMotion):
(webkitWebViewBaseDragLeave):
(webkitWebViewBaseDragDrop):
(webkitWebViewBaseDragAndDropHandler):
(dragExitedCallback): Deleted.
(webkitWebViewBaseStartDrag): Deleted.
* UIProcess/API/gtk/WebKitWebViewBasePrivate.h:
* UIProcess/gtk/DragAndDropHandler.cpp: Added.
