* platform/win/DragImageWin.cpp: Moved createDragImageForLink from DragClient

This patch contains the remaining work to support
a WebKit window as drag source on Windows.
I've added the code to generate the image for dragging a link as
well as the steps necessary to package the HBITMAP into a SharedMemory
object and send it over to the UI process where DoDragDrop is performed.

* UIProcess/WebPageProxy.cpp:
(WebKit::WebPageProxy::setDragImage):
(WebKit::WebPageProxy::startDragDrop):
* UIProcess/WebPageProxy.h:
* UIProcess/WebPageProxy.messages.in:
* WebProcess/WebCoreSupport/WebDragClient.cpp:
(WebKit::WebDragClient::startDrag): Made startDrag for
platforms other than Windows and Mac.
* WebProcess/WebCoreSupport/WebDragClient.h:
* WebProcess/WebCoreSupport/mac/WebDragClientMac.mm:
(WebKit::WebDragClient::startDrag):
* WebProcess/WebCoreSupport/win/WebDragClientWin.cpp: Added.

This object implements the IDropSource interface.
