This makes use of the `periph_timer_query_freqs` feature: 1. It does choose the closest frequency supported before calling timer_init() in the ztimer_periph_timer backend. 2. It does make use of the actually chosen frequency when using `ztimer_convert_frac`. 3. It does `assert()` the frequency is within 5% of the specified when no frequency conversion is performed or `ztimer_convert_shift_up` is used.
