[Bazel] Emit Type Definitions

I tried to add `--emit-tsd [some file path]` to the linker options, however the build complained that `tsc` is not available from the emscripten workspace. From my understanding, [these lines](https://github.com/emscripten-core/emscripten/blob/ffeb76137e765a0023de2635420a4827ca15106d/tools/emscripten.py#L646) check that `tsc` is globally available or via npm. I attempted a few things to incorporate typescript via rules_js from Aspect Build without much success. Without sandboxing and with a global installation of typescript, it works just fine.

What is the recommended approach to maintain sandboxing when emitting types?
