Give queued_events_flush_all() responsibility for flushing log cbs

This requires that when a log cb happens, the event for flushing
queued events is scheduled, so we also add the necessary machinery
to have that happen.

Note that this doesn't actually help with logs from outside the main
thread, but those were already suppressed: see #25987 for a ticket
tracking that issue.
