This removes a bunch of custom code from GfxInfo to obtain screen information, and instead collects that screen information in ScreenManager. This, apart of removing duplicated code, has the extra benefit of reporting multi-monitor information on GTK (and potentially in the future reporting scale and refresh rate properly as well, I've kept the telemetry as it was on that regard).
