Returns an Array of Addrinfo objects for all local IP addresses
(IPv4 and IPv6) on every network interface, matching CRuby's API.
Backed by getifaddrs(3) on POSIX and GetAdaptersAddresses on
Windows (requires iphlpapi.lib, added to the Windows linker libs).
The HAL returns binary sockaddr strings; src/socket.c wraps each
into Addrinfo so the wrapping code stays platform-agnostic.
Resolves the second error reported in #5659 (after the IO.select
fix from the HAL split): "undefined method 'ip_address_list' for
Class". Issue #5659 itself is closed; this lands the missing API.
Ref #5659.

Winsock APIs (socket, bind, connect, accept, recv, send, ...) report
errors via WSAGetLastError() and do not set errno, so mrb_sys_fail
on Windows was reading a stale or zero errno. Result: every socket
failure raised SystemCallError with errno 0 ("Success") instead of
the appropriate Errno::* class.
Add mrb_hal_socket_set_errno_from_last_error() to the HAL:
- POSIX: no-op (failed calls already set errno)
- Windows: maps WSAGetLastError() to a POSIX errno via wsa_to_errno()
with 32 cases covering the common Winsock error codes; unmapped
codes fall back to EIO. Each case is #ifdef-guarded against older
MSVC CRTs that lack a particular Exxx.
In src/socket.c, route the 22 socket-API failure sites through a new
sock_sys_fail() helper that calls the HAL translator before
mrb_sys_fail. Also fix mrb_hal_socket_set_nonblock() on Windows,
which was returning -1 without setting errno after ioctlsocket
failure.
POSIX behavior unchanged (verified: TCPSocket connect refused ->
Errno::ECONNREFUSED, bind to privileged port -> Errno::EACCES, bad
sockopt -> Errno::EOPNOTSUPP).
Closes#6819, reported by Asmod4n.

rename all HAL functions from mrb_<feature>_hal_<name>() to
mrb_hal_<feature>_<name>() for better grouping and clarity. this makes all
HAL functions immediately identifiable with the mrb_hal_* prefix.
