Tweak module resolution failed lookup watching

[sheetalkamat]

This simplifies unnecessary extension watching from long ago when we had different resolutions based on .ts and .js files
Before we would never watch directories like c:/typescript/node_modules or /user/username/typescript/node_modules because we didnt watch folders like c:/typescript or /user/username/typescript. Now changed to watch node_modules in root folder. (We wont watch it at root unless tsconfig is at the root)

This should help with some of the npm ci issues in repo encountered if typescript repo was at root or in another folder .

Can you explain why these were missing before and are added now? I don’t quite see why from the implementation change.

Sorry i thought this was also handled by "canWatchFileOrDirectory" thing but we had logic for watching node_modules/@types at tsconfig or jsconfig directory as well which has some issues when it is /. I will look more into this and fix any other issues with config at root directory.

@typescript-bot pack this

Heya @DanielRosenwasser, I've started to run the tarball bundle task on this PR at f64f2ad. You can monitor the build here.

[typescript-bot]

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/150952/artifacts?artifactName=tgz&fileId=44CA3A0E1125714E6701D3D003A9E7B950EED15E8D0F039F858E806CF328726202&fileName=/typescript-5.1.0-insiders.20230324.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

Closing this in favor of #53591 which i am still working on
