Fix race between DPI and window size

Because the display scale factor and the window size are sent in two different
IPCs, and because the window size (ViewMsg_Resize) may be delayed (to avoid
spamming the renderer with resize messages while dragging), the renderer can
think it's using a different resolution than it is.

This merges the ViewMsg_ScreenInfoChanged and ViewMsg_Resize messages,
so that the renderer cannot not have a consistent view of the window size and
DPI.
