Display project deletion audit event in group audit event log

What does this MR do and why?

This change implements project deletion audit events at the group level. When a project is deleted from a group the audit event is visible in the group's audit log rather than being lost with the deleted project.

The implementation modifies the existing project_destroyed audit event to add more details about the project that was deleted.

The implementation modifies the existing project_deletion_marked audit event to scope the events to the parent group for group projects.
