Add refactored stream destination editor vue component

What does this MR do and why?

Now that we have 1 api for all the different streaming destinations, we're adding 1 editor for all of them (AWS|GCP|HTTP).

This work leverages the previous work in the series, so you can list and delete destinations here. The other actions will be taken care in upcoming MRs.

The whole work is under use_consolidated_audit_event_stream_dest_api FF.
