SystemUI: screenshot: Also post a notification with a preview

Make each notification unique so user can take many and still quick access em all
This does not need a setting side as the notification channel is blockable
No notification actions for now -
the file can be accessed by pressing the notification. Gallery can manage it just fine

    Subject: base: SystemUI: Also use TAG to count group notifications

    So screenshot / screenrecord don't count each other's notifications.
    Fixes non dismissing group summary when there is a notification from the other service
    Also improve some code while at it
