close#6080
Changelog
- add: implement `SuggestionsRepo.insertAll` as a batch SQL insert
- update: `search/getSuggestionsDatabase` returns empty suggestions. Currently, the method is only used at startup and returns the empty response anyway because the libs are not loaded at that point.
- update: serialize only global (defined in the module scope) suggestions during the distribution building. There's no sense in storing the local library suggestions.
- update: sqlite dependency
- remove: unused methods from `SuggestionsRepo`
- remove: Arguments table
# Important Notes
Speeds up libraries loading by ~1 second.

Implement new Enso documentation parser; remove old Scala Enso parser.
Performance: Total time parsing documentation is now ~2ms.
# Important Notes
- Doc parsing is now done only in the frontend.
- Some engine tests had never been switched to the new parser. We should investigate tests that don't pass after the switch: #5894.
- The option to run the old searcher has been removed, as it is obsolete and was already broken before this (see #5909).
- Some interfaces used only by the old searcher have been removed.
Updated the SQLite, PostgreSQL and Redshift drivers.
# Important Notes
Updated the API for Redshift and proved able to connect without the ini file workaround.
