Generated lib*.d.ts files differ from the files in TypeScript SDK

[deniskovalchuk]

TypeScript Version: at least 3.9.7 and 4.0.5

The lib/lib*.d.ts and built/local/lib*.d.ts files contain mixed line breaks (LF/CRLF) and differ from the files in the TypeScript SDK, which contain only LF.

Steps to reproduce

Build LKG or local on any operating system.

git clone --config core.autocrlf=input https://github.com/microsoft/TypeScript.git
cd TypeScript
npm ci
gulp LKG

Expected behavior:

Consistent line breaks in lib*.d.ts files and no differences from the TypeScript SDK.

Actual behavior:

Mixed line breaks.

Post #51387, this one is definitely fixed as the problem here was the way we combined things with gulp (among other things). In the new build, the entirety of built and lib now consistently use LF line endings.

@jakebailey, I've tested TypeScript 5.1.6 and can confirm that this problem has been fixed. Thank you!
