[riot-notifications] [RIOT-OS/RIOT] sys/ztimer: Potential footgun when mixing timestamps of ztimer clocks (#16698)

In #16327 I proposed to introduce a stop watch that also might be used as a wall clock (which is a stop watch running since 1.1.1970 ;)). This approach also solves an important power management problem: currently ztimer doesn't know if someone is measuring time differences.

So I'd like to opt for @maribu's alternative 5. All other alternatives will introduce drawbacks in terms of power management and/or complexity.
