Lingao Meng 3d20844903 arch/sim: Add AF_LOCAL support to host usrsock
The sim host usrsock backend only accepted INET/NETLINK domains and
translated socket addresses through plain struct sockaddr. That prevents
simulated applications from using POSIX AF_LOCAL sockets through the
standard socket API when CONFIG_NET_USRSOCK is used.

Add AF_LOCAL address conversion for struct sockaddr_un, allow PF_LOCAL
sockets through usrsock, handle NuttX socket type flags, and poll host
descriptors from the sim usrsock work item so nonblocking
connect/read/write readiness is reported back to NuttX. Use
sockaddr_storage for native address translation so larger address
structures are not truncated.

Testing:

  - Host: Ubuntu 22.04 x86_64.

  - Board/config: sim:nsh with CONFIG_NET_USRSOCK=y and
    CONFIG_EXAMPLES_HELLO=y.

  - make clean && make -j16.

  - Ran a temporary hello example that connected to host AF_UNIX
    SOCK_STREAM and SOCK_SEQPACKET sockets through NuttX socket(),
    connect(), write(), and read(). Both received pong and printed
    "AF_LOCAL usrsock test passed".
