Merge #3296

3296: vscode: bump TypeScript version r=matklad a=Veetaha

There is a new [`type-only` import and export feature](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#-type-only-imports-and-export), but let's keep our codebase as simple as it is now.
Also, top-level await 🎉, though with a caveat ))
