Fix glue for ClipboardHostMsg_ReadAvailableTypes.

Since we no longer plan on using this message to service both drags and
pasteboard requests, update the glue to call ui::base::Clipboard directly.
Eventually, the remaining functions in ClipboardDispatcher will also be
moved and/or deleted and the empty class removed.
