[CS] Define DisplayMetricsRepo and use it for QsFrameTranslateImpl.

CentralSurfacesImpl updated the display metrics on configuration change
(see #updateDisplaySize), so the new repo does the same.

Removing QsFrameTranslateImpl's usage of CentralSurfaces is necessary to
make NotificationPanelViewController a singleton.
