Remove dead ViewMsg_{Zoom, DidZoomUrl}

Remove dead ViewMsg_{Zoom, DidZoomUrl}

These messages and surrounding infra seem to be left over from prior
implementations of various pieces of zoom functionality (e.g., zooming
in plugins). The code being removed is never exercised:

- The browser-side entrypoint for sending ViewMsg_Zoom is
  RenderViewHost::Zoom(), which is never called.
- The renderer-side entrypoint for sending ViewMsg_DidZoomUrl is
  RenderViewImpl::zoomLevelChanged(), which is never called.

I noticed this while investigating crbug.com/673065.
