[Security Solution] JSON diff view PoC (simplified)

[banderror]

Summary

A simplified version of #171750 without some extra code that's not 100% necessary for rendering rule JSON diffs:

• Diffs for individual fields
• Expanders and accordions

Additionally, this version memoizes all diff calculations which makes re-rendering of each tab with diffs much faster.
