[Unified Search] Move autocomplete logic to unified search plugin

[nlatipov]

Summary

This PR is solves Issue: #128383

Motivation:
After PR #127651 is merged, next step is move the autocomplete folder to the unified_search plugin. No extra functionality is going to be added (or cleanups or improvements).

What was done:

1. data/plugin/autocomplete folder was moved into unified_search;
2. data/plugin/server/autocomplete folder was moved into unified_search;
3. The following part was moved from from the Data Plugin runtime contract to UnifiedSearch Plugin

  autocomplete: this.autocomplete.start(),

5. Related Static and Runtime imports were updated
6. Added the unifiedSearch plugin as a dependency to plugins that require plugins (Kibana.json)
7. Registered a unifiedSearch plugin in the i18n (translations) plugin
8. data/server/config_deprecations.ts file was moved into unified_search/server and added renameFromRoot for autocomplete;
