Some first thoughts ...

I like this approach! It's heading more in the direction of *it simply works*.

I would change this to `#if MODULE_ZTIMER_PERIPH_RTT`. This should be the correct way to check whether `ZTIMER_MSEC` should be backed by `periph_rtt`.

On the first glimpse, this looks like `xtimer` configuration is creeping into `ztimer`. But I don't have any idea how to implement this the *clean way*.
