wasm: increase default thread stack size to 1 MB

The default stack size for the [main thread is 1 MB as specified by linker options](38cf49dde8/compiler/rustc_target/src/spec/base/wasm.rs (L14)).
However, the default stack size for threads was only 64 kB.

This is surprisingly small and thus we increase it to 1 MB to match the main thread.
