Only when typings file change for the project, schedule the update for the project

[sheetalkamat]

This avoids unnecessary project updates, project updated in background on which editor normally sends error request so multiple program updates and unnecessarily invalidating resolutions is avoided.
Fixes #39326

@typescript-bot pack this

Heya @sheetalkamat, I've started to run the tarball bundle task on this PR at 6d543ea. You can monitor the build here.

[typescript-bot]

Hey @sheetalkamat, 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/93822/artifacts?artifactName=tgz&fileId=C2CB9F255EE3292BA69CCD1F39BED9A6DE2BCEA1815B72ACC1B42EC063ABD0C102&fileName=/typescript-4.2.0-insiders.20210121.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]".;

Working, thanks so much!

Are there any scenarios we should expect to be affected in VS besides adding new typings? I don't foresee any issues in that case.

Very nice

No it just improves when the program updates in background in tsserver so technically nothing should change apart from better perf with respect to avoiding unnecessary updates.
