some apps are using `emscripten_num_logical_cores`, which iirc maps to `navigator.hardwareConcurrency`, as a hint to decide the default number of threads. cf. https://github.com/ffmpegwasm/x264/commit/266eb136adc29f80669d35d0564cd7ae7a0bd29d i guess it makes sense to provide an...

the current wasi-libc implementation seems to use `wasi_proc_exit` for both of thread exit and process exit. i guess it's simpler to distinguish them.

i guess choices are: a-1. use `wasi_proc_exit` for process exit. introduce `wasi_thread_exit` for thread exit. a-2. use `wasi_proc_exit` for process exit. introduce no extra api for thread exit. just make...
