build: enable esmoduleinterop option in scripts

Similar to the `/tsconfig.json` and the `tools/tsconfig.json`, we should
enable the `esModuleInterop` from TypeScript in the `scripts/` directory.

This is necessary to ensure that scripts part of both compilations. e.g. when
a file in `scripts/` imports from `tools/` are compatible without needing
two coordinated compilations (using e.g TS project references..). In general
enabling the interop means more consistency in the repo.

Then only remaining exception are the schematics which we can clean-up in the
future when we ship them as ES modules.
