[Bug] Many duplicates in minified tsWorker.js leading to large file

Reproducible in vscode.dev or in VS Code Desktop?

• Not reproducible in vscode.dev or VS Code Desktop

Reproducible in the monaco editor playground?

• Not reproducible in the monaco editor playground

Reproduction Steps

1. Open a compiled version of the file min/vs/language/typescript/tsWorker.min.js CDN Example
2. Optionally copy the code in a VS Code window
3. Search for interface CanvasDrawPath {
4. Note that the definition is found twice
5. This duplication issue is the case for a lot of code

Actual (Problematic) Behavior

The minified version of tsWorker.js is around 4.6 MB I want to use the Monaco editor in a web extension, but this allows a maximum file size of 4 MB

If the code duplication is fixed, that would reduce the filesize enough to get below 4 MB

Expected Behavior

No duplicate code generated during the build

I'm not sure if this is easy to fix - I guess the typescript compiler ships various libraries (like ES3/ES6).

I think, first analyzing and removing duplicate lines can be done.
Then we can look at the condition, if it solves, then good, otherwise need to look down into deep for solution.
