Ref: #38182
Ref: https://twitter.com/bradleymeck/status/1380643627211354115

Added JSDoc typings to lib/util. Most of the typings are pretty simple and direct, all the isThing methods have been typed using type predicates.

callbackify is a bit complex, for this I used the new Leading Rest elements in tuple types to infer types.

Before:

After:

There are still some errors with checkJs enabled that I'm not sure how to fix since we are mutating the original type:

No need to fix all the checkJs errors for now! it is going to be an iterative process that will get easier as more types are added throughout core.

Many of the util functions are deprecated.
Should we use jsdoc's @deprecated tag to mark them as such?

Added @deprecated tags since Typescript does support them (https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-0.html#-deprecated--support)

It is supported by TypeScript but the goal of JSDoc in core files is not to duplicate the public-facing documentation. Maybe it's fine in this case, because we don't use these functions in core, but we have to be careful about this (avoid too much duplication, focus on typings and other small changes that help core developers).
