Bug 28293 -  [Chromium] event.datatransfer.getdata("text/uri-list") is treated the same as getdata("URL")

Reviewed by David Levin.

WebCore: 

Change ChromiumDataObject such that it treats types "URL" and "text/uri-list"
correctly for event.dataTransfer.getData/setData. Currently both are treated
as synonyms, but for "URL", getData is supposed to only return the first valid URL
contained within the data for "text/uri-list" (see HTML5 spec).

correctly for event.dataTransfer.getData/setData. Currently both are treated
as synonyms, but for "URL", getData is supposed to only return the first valid URL
contained within the data for "text/uri-list" (see HTML5 spec).
        
Layout test checks various combinations in a drag-n-drop operation.
Skipping on all other platforms since they don't implement this correctly, either.
