[wasm64] Cast BigInt argument to i64 Number (#17613)

Fix argument type and struct access of various functions on WASM64:

    system
    gethostaddr
    gethostbyname
    gethostbyname_r
    getaddrinfo
    getnameinfo
    connect
    bind
    sendto
    doStat (internal helper for stat calls)
    pwrite
    pread
    read return value
