If we're going to add a new type here instead of returning the HistoryLoadType
enum, FrameLoadTypeBackForward should get renamed to
FrameLoadTypeHistoryDifferentDocument. Given how similarly they're handled,
though, I think it might be better to not add a FrameLoadType, keep the
HistoryLoadType enum and store it on FrameLoadRequest.

I went with providing the HistoryLoadType to the load method.

     FrameLoadTypeReload,
     FrameLoadTypeSame, // user loads same URL again (but not reload button)
     FrameLoadTypeRedirectWithLockedBackForwardList,
