skipLibCheck, specific skipLibCheck

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Add an ability to apply skipLibCheck for specific files and folders.

📃 Motivating Example

For now, enabling skipLibCheck will skip errors in d.ts files in all places (codebase/node_nodules). But that's sometimes not needed for actual codebase. Or maybe there is some exotic case when a developer doesn't want to skip some specific lib from node_modules.

💻 Use Cases

In my case I don't want to skip d.ts files in my codebase. Ideally even skip some specific libs from node_modules with broken/not compatible with tsconfig types.
BTW great examples of how skipLibCheck works are located in https://github.com/omril321/skip-lib-check-examples

This seems like effective a duplicate of #30511 - by far the most common thing we hear is that people want to check "their" files (for some definition of "theirs") but exclude "other" files (for some definition of "other"). I think the problem is simply defining a coherent way to distinguish theirs/others.
