grimshot: Add a separate flag for notifications

Make notifications a separate flag. Personally, I trigger grimshot
myself most of the time (via sway bindsym) rather than by some external
means, so I don't need to be notified of it happening.

However, keep a flag with this functionality there for those scenarios
there it's necessary to inform the user.

Also print the file location when saving the screenshot.
