[Security Solution][API testing] Move and restructures Basic detectio…

…n engine tests (elastic#171531)

## Summary

Following the initial work in this
elastic#166755
- Addresses part of elastic#151902 for
basic detection engine-related tests
- Introduced a new license folder to hold the `Basic` Ess tests and the
`Essentials` Serverless tests, is called `basic_essentials_license`
- Added new base configurations files for
`serverless/config.base.essentials` and `ess/config.base.basic`
- Moved the utility files associated with Basic tests to the new
directory `security_solution_api_integration`. Files not actively used
in the previous folder were moved, while duplicate files remained in
their original positions.
- Updated the CodeOwner file for the newly moved tests
- Old/new group details, decisions, and execution time are mentioned in
this
[document](https://docs.google.com/document/d/1CRFfDWMzw3ob03euWIvT4-IoiLXjoiPWI8mTBqP4Zks/edit)
- The **Privileges** Tests are skipped in Serverless now until the FTR
Roles [PR](elastic#170131) gets merged
