Increase default Wasm stack to 1MB

This commit increases the default Wasm stack to 1MB from the default of 1 Wasm page which equal 64KB. This seems like a reasonable default size while at the same time not overly large. Also, Rust lang seems to be favouring this default as well: [rust-lang#50083]. [rust-lang#50083]: https://github.com/rust-lang/rust/pull/50083
