`embassy-time`: add missing `Debug` & `defmt::Format` derives

`defmt::Format` is *not* implemented for `MockDriver` and
`InnerMockDriver` because the former contains the latter and the latter
is using `Queue` from `embassy-time-queue-utils` which so far does not
have a `defmt` dependency. since this is just a mock driver it shouldn't
be relevant if it has no `defmt::Format` impl.
