Replace `superstruct` with ESM-compatible fork `@metamask/superstruct`

[MajorLift]

Explanation

As part of the Wallet Framework Team's OKR (Q2 2024 O3KR4) for upgrading TypeScript to v5.0+ in the core monorepo, we are updating dependencies of the core repo so that they generate builds and type declarations for both CJS and ESM.

This requirement applies to nested dependencies as well, so we are also replacing superstruct with the ESM-compatible fork @metamask/superstruct in all core dependency packages.

Description

• Replace superstruct dependency with @metamask/superstruct v3.0.0.
• Replace all superstruct import statements with @metamask/superstruct
• Bump @metamask/utils to v8.4.0.
• If feasible without too much additional work, set module and moduleResolution tsconfig options to NodeNext and TypeScript to v5.
• Create new release applying these changes.
