chore(nim): task simplification (#13956)

This PR slightly simplifies the way tasks are passed between threads,
removing some unnecessary boilerplate while improving type safety by
removing casts.

This approach works because `nimcall` turns a `proc` into a simple
pointer which just like `cstring` is safe to pass between threads.

Further simplification is possible, but left for a future PR.
