Organization removal analytics (#97672)

Redo of #97378 after endpoints moved to core, easier to start fresh. 

When performing an org removal, we write the removal event to the
organization audit log. That's great if the organization is restored,
but after org removal is completed we purge the organization's audit
log. Finding the time of deletion and organization slugs when they're
gone from the database is more difficult than necessary and this
occasionally appears in customer support requests.

We have existing organization_created and organization_joined events in
analytics, so I'm adding an organization_removed to the mix.
