[serverless] Create Observability Serverless plugin (#156118)

> Derived from https://github.com/elastic/kibana/pull/153274
> Builds upon https://github.com/elastic/kibana/pull/155582

## Summary

This PR creates the Serverless Observability plugin, based on the work
from https://github.com/elastic/kibana/pull/153274:

- creates the plugin,
- adds API to hide the solution navigation from Enterprise Search,
- calls that API if the chrome style is `project`.
