Add auto resolve JSON schemas

What does this MR do and why?

Adds JSON schemas for four new security profile configuration types: SAST VR, SAST FP, SD FP, and vulnerability enrichment.

Properties and limits come from the this table. Properties whose type or shape is still undefined (vulnerability_context_metadata, business_context, target_branch, the percentage form of FP confidence) are left out for now.
