Fuchsia: Enable perFrameWindowSizeQuery by default

Fuchsia won't return VK_ERROR_OUT_OF_DATE_KHR after a size change, so we need to check every frame. In fact we don't even tell Scenic what the new size is during resize, because it does not care - the surface size determines the "window size", not the other way around.
