Merge dev/socket into main (#1393)

Implement more socket APIs, refer to #1336 and below PRs:
- Implement wasi_addr_resolve function (#1319)
- Fix socket-api byte order issue when host/network order are the same (#1327)
- Enhance sock_addr_local syscall (#1320)
- Implement sock_addr_remote syscall (#1360)
- Add support for IPv6 in WAMR (#1411)
- Implement ns lookup allowlist (#1420)
- Implement sock_send_to and sock_recv_from system calls (#1457)
- Added http downloader and multicast socket options (#1467)
- Fix `bind()` calls to receive the correct size of `sockaddr` structure (#1490)
- Assert on correct parameters (#1505)
- Copy only received bytes from socket recv buffer into the app buffer (#1497)
