feat: organizational, add support for single-account deployment (#128)

small steps to go for organizational single-account setup as required by
many customers; ⚠️ scanning still not supported
- added use-case explanation
- added `deploy_benchmark_organizational` to deploy `cloud-bench` module
on single account OR stackset (organizational)
- added test (wip, evaluating if required time makes sense)

<!--
Thank you for your contribution!

## General recommendations
Check contribution guidelines at
https://github.com/sysdiglabs/terraform-aws-secure-for-cloud/blob/master/CONTRIBUTE.md#contribution-checklist

For a cleaner PR make sure you follow these recommendations:
- Review modified files and delete small changes that were not intended
and maybe slip the commit.
- Use Pull Request Drafts for visibility on Work-In-Progress branches
and use them on daily mob/pairing for team review
- Unless an external revision is desired, in order to validate or gather
some feedback, you are free to merge as long as **validation checks are
green-lighted**

## Checklist

- [ ] If `test/fixtures/*/main.tf` files are modified. I have updated:
    - [ ] the snippets in the README.md file under root folder.
- [ ] the snippets in the README.md file for the corresponding example.
- [ ] If `examples` folder are modified. I have updated:
    - [ ] README.md file with pertinent changes.
- [ ] `test/fixtures/*/main.tf` in case the snippet needs modifications.
- [ ] If any architectural change has been made, I have updated the
diagrams.
