In src/vendor/node/util.ts module remove imports of inspect and format, instead implement them inline in the src/vendor/node/util.ts module itself. Create a minimal implementation, which mimics the original, does not have to be as comprehensive, make the implementation up to few dozen files long, the shorter the better.

Reference implementation of inspect and format: https://github.com/nodejs/node/blob/main/lib/internal/util/inspect.js
