change socket / file descriptor checks on windows

based on discussion in https://github.com/libressl/portable/issues/266
and https://bugs.python.org/issue23524 adjust the compat layer for
Windows to use _get_osfhandle in combination with
_set_thread_local_invalid_parameter_handler if applicable to more
reliably determine if a handle is a socket, file, or closed socket.

This prevents assertions when calling tls_close on an already-closed
socket.
