[serverless] Add ability to disable certain plugins for Serverless. (#155583)

> Derived from https://github.com/elastic/kibana/pull/153274

## Summary

This PR extracts configuration settings for enabling/disabling plugins
in Serverless projects based on current requirements.

It seemed prudent to create an independent PR to K.I.S.S, rather than
include in PRs with more ornate changes, (e.g.
https://github.com/elastic/kibana/pull/155582)
