Update DataTransfer.Files upon change to it's items list

Refactored "blink::DataTransfer" class to update "files_" member when
it's DataObject's item list is changed, instead of doing the same in
the files getter. This change ensures that files is updated
immediately when the DataTransfer's item list changes.

This fixes the issue where if a reference to DataTransfer.files is
stored in a separate JS variable, then any file items added to that
DataTransfer object are not reflected in the stored JS variable, until
the DataTransfer object's files getter is invoked. The issue is not
present in Safari and Firefox.
