Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Follow the posix standard:
If no messages are available to be received and the peer has
performed an orderly shutdown, recv() shall return 0.

conn->sendsize is used in rpmsg_socket_ept_cb() and
rpmsg_socket_connect_internal(), the connected event may be missed
as stated below:
1. in rpmsg_socket_connect_internal(), judge conn->sendsize == 0
and prepare to wait sendsem;
2. interrupt by rptun thread, rpmsg_socket_ept_cb() is called to
update conn->sendsize and post the sendsem, but the no one wait
rx sem yet, so not post (see rpmsg_socket_post());
3. return to rpmsg_socket_connect_internal() to wait the sendsem, but
has miss the connected event.
So add recvlock in rpmsg_socket_connect_internal() also.

Use PRIx64 which defines the width correctly regardless or architecture.
Fixes build error:
rpmsg/rpmsg_sockif.c:610:57: error: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'uint64_t' {aka 'long unsigned int'} [-Werror=format=]

recvmsg() will incorrectly return 0 if the count of sema before waiting is greater than 0,
This commit will reinitialize the sema count before waiting:
1181 static ssize_t rpmsg_socket_recvmsg(FAR struct socket *psock,
1182 FAR struct msghdr *msg, int flags)
1183 {
...
1255 ret = net_sem_timedwait(&conn->recvsem,
1256 _SO_TIMEOUT(conn->sconn.s_rcvtimeo)); // recvsem.sem_count == 1; return 0
...
1264 if (!conn->recvdata) // recvdata not consumed; goto else
1265 {
1266 ret = conn->recvlen;
1267 }
1268 else
1269 {
1270 conn->recvdata = NULL;
1271 }
...
1282 return ret; // BUGON! incorrectly return 0 to user
1283 }

The rpmsg addr get from socket accept has rp_family=0, which is not
intended, to avoid wrong logic in other place, set the rp_family
in ns_bind function.
