util: use primordials consistently in inspect.js

[Ayoub-Mabrouk]

Replace native array methods (.push, .pop, .splice, .slice) withprimordials (ArrayPrototypePush, ArrayPrototypePop, ArrayPrototypeSplice,ArrayPrototypeSlice) throughout lib/internal/util/inspect.js for consistency and security.

This improves protection against prototype pollution and aligns with the primordials pattern used throughout the codebase.
