[build] Remove chat solution from stateful artifacts (#215430)

Removes `private` packages in the `chat` group from releasable
artifacts.

In order to facilitate functional tests against the chat solution, we
will not remove packages in snapshot builds until
https://github.com/elastic/kibana/issues/215582 is completed.

Closes https://github.com/elastic/kibana/issues/213468
