unix: Update port to use the new event functions.

Browse Source 
Necessary to get coverage of the new event functions.

Deletes the case that called usleep(delay) for mp_hal_delay_ms(), it seems
like this wouldn't have ever happened anyhow (MICROPY_EVENT_POOL_HOOK is
always defined for the unix port).

This work was funded through GitHub Sponsors.
