[FIX] ir.cron: restore INFO logging of job execution

The "Starting job X" and "Job X done" logs are very useful to monitor
cron executions over time, or to detect a cron job that has been running
for a long time.

Those logs were dropped by mistake in #62124 - this patch restores them.

closes odoo/odoo#70921
