Adds audit event for audit event filter creation

What does this MR do and why?

Creates audit event when event type filter is created.

How to set up and validate locally

1. create event type filters https://docs.gitlab.com/ee/administration/audit_event_streaming.html#event-type-filters

mutation createEventTypeFilter {
  auditEventsStreamingDestinationEventsAdd(input: {
    destinationId: "GID",
    eventTypeFilters: ["filter_1", "filter_2"]
  }){
    errors
    eventTypeFilters
  }
}

2. Check gdk_host/admin/audit_logs for audit events created.
3. verify audit event is created with correct attributes.
