[mutter/wip/carlosg/no-scaled-views-check-in-thread: 22/23] backends: Store whether views are scaled in MetaViewportInfo

[Marge Bot <marge-bot src gnome org>]

commit 24dbfbfcf2c0b2242221615ffc0d69aba801df4e

    backends: Store whether views are scaled in MetaViewportInfo
    
    We need to pass this info from the main thread, as that pokes the
    MetaMonitorManager underneath. Store it in the MetaViewportInfo
    so that the input thread can use this information.
