feat: Add support for scope_offset_compressed signature type

What does this MR do and why?

The new scope_offset_compressed algorithm is used for calculating more stable signatures for uniquely identifying vulnerabilities as they move around a codebase.

• Overview of Advanced Vulnerability Tracking
• Details on algorithm [internal only]

This MR must be merged before we can product the new signatures types within Category:SAST analyzers or the reports will be rejected.

Relates to [internal only] https://gitlab.com/gitlab-org/gitlab/-/issues/404529+s

How to set up and validate locally

1. Update a project with SAST vulnerabilities CI configuration to point at patched semgrep container:

   semgrep-sast:
     image:
       name: registry.gitlab.com/gitlab-org/security-products/analyzers/semgrep:bump-tc

2. Run pipeline
3. Ensure report was ingested successfully
4. Open rails console
5. Check Vulnerabilities::FindingSignature.where(algorithm_type: 4).count.positive?
