[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

Additional Context

Start with the generated min/vs/language/typescript/tsWorker.min.js file and the reported duplicate interface CanvasDrawPath definition, using the CDN example to reproduce the size and duplication. Trace the build inputs that produce tsWorker.js and verify that the duplicate code is removed without changing the worker output; done means the minified file is below the reported 4 MB limit and no longer contains the duplicated definition.
