Move a bunch of stuff out of WebContents. I removed a bunch of render view host pass-throughs and just made the callers call the render view host directly. I don't think we're trying to isolate the layers to this degree, and WebContents is so big these just added noise.

I removed the RenderViewHost->WebContents->SavePackage pass-through by using a delegate that the SavePackage implements (like we already do for find in page). I also noticed some file upload stuff wasn't used at all and removed it.
