Rollup merge of #138757 - rust-wasi-web:wasi-thread-stack-size, r=alexcrichton
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](https://github.com/rust-lang/rust/blob/38cf49dde8a5b0b284bb6dffd423d223c9f8f7a3/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.
