This fixes screen sizes when using mutter with fractional scaling, and shouldn't change behavior otherwise. Without this patch, mutter with scale at 150% reports: [screen.width, screen.height] == [ 1920, 1080 ] With this it reports the proper [ 2560, 1440 ]. The bug that caused us to introduce it was long fixed in gtk itself, as I understand it, and ScreenGetterGtk is also what's used everywhere else on Wayland. Re-implement GetScreenForWindow in a way that works for ScreenGetterGtk too, to avoid regressing any functionality on mutter. Depends on D186341 Differential Revision: https://phabricator.services.mozilla.com/D186342
