Notification: Fence the *display* update in an attempt to avoid upsetting some boards... (#10083)
Re: https://github.com/koreader/koreader/issues/9806#issuecomment-1416827447

Depends on https://github.com/koreader/koreader-base/pull/1576

Includes assorted cosmetics tweaks related to duplicate `setDirty` calls when instantiating widgets that already have an `onShow` handler doing it. (I left widgets doing it in `update` instead of `init` alone, on the assumption that callers *may* be relying on that behavior when updating widgets at runtime. This might actually never matter, and it certainly didn't for ScreenSaverWidget, which is why I removed it from there ;p).
