This PR makes `event_timeout` and `event_timeout_ztimer` two distinct pseudomodules, where the only api difference is in the init function. If only `event_timeout_ztimer` is selected then no default ZTIMER backend is selected and the old init function is not implemented. If only `event_timeout` is selected then `xtimer` is used unless `ztimer_usec` is included. In which case the `xtimer` wrapper on top of `ztimer` is used and `xtimer` is not directly selected. This allows for the legacy api to be supported with `ztimer_usec` as a drop-in replacement. If `event_timeout` and `event_timeut_ztimer` are selected then `event_timeout` SRC file is excluded from compilation.
