Increase default native stack size (#2332)

Browse Source 
Calling `__wasi_sock_addr_resolve` syscall causes native stack overflow.
Given this is a standard function available in WAMR, we should have at least
the default stack size large enough to handle this case.

The socket tests were updated so they also run in separate thread, but
the simple retro program is:

```C
void *th(void *p)
{
    struct addrinfo *res;
    getaddrinfo("amazon.com", NULL, NULL, &res);
    return NULL;
}

int main(int argc, char **argv)
{
    pthread_t pt;
    pthread_create(&pt, NULL, th, NULL);
    pthread_join(pt, NULL);
    return 0;
}
```
