Update thread and futex APIs to work with Emscripten
This updates the thread and futex APIs in `std` to match the APIs exposed by Emscripten. This allows threads to run on `wasm32-unknown-emscripten` and the thread parker to compile without errors related to the missing `futex` module. To make use of this, Rust code must be compiled with `-C target-feature=atomics` and Emscripten must link with `-pthread`. I have confirmed this works well locally when building multithreaded crates. Attempting to enable `std` thread tests currently fails for seemingly obscure reasons and Emscripten is currently disabled in CI, so further work is needed to have proper test coverage here.
