UDP and PKT will hold the dev lock and conn lock when calling back the
protocol stack from the network dirver. At this time, if the poll_notify
notifies usrsock_server and executes poll_teardown, a conn double lock
will appear. so we changed the lock to a recursive lock

Our net socket connection allocations are powerful but redundant
because they're implemented once in each protocol. This is not good for
further optimizing and extending to other allocations, so maybe we can
add a common implementation for the usage.
Impact:
1. We add a `struct net_bufpool_s` as pool descriptor, which may use a
little bit more memory than previous implementation (~28Bytes).
2. We share same functions between pools, so code size may shrink under
some scenarios.

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

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Squashed commit of the following:
net/icmp: Finishes off icmp_recvfrom().
net/icmp: Add readahead support for IPPROTO_ICMP sockets.
net/icmp: Add poll() support for IPPROTO_ICMP sockets.
net/icmp: Add a connection structure for IPPROTO_ICMP sockets.
net/icmp: Implements sendto for the IPPROTO_ICMP socket.
net/icmp: Move icmp_sendto() and icmp_recvfrom() to separate files. They are likely to be complex (when they are implemented).
net/icmp: Hook IPPROTO_ICMP sockets into network. Fix some naming collisions. Still missing basic ICMP send/receive logic.
configs: apps/system/ping current need poll() enabled.
configs: All defconfig files that use to enable low-level support must now enabled CONFIG_SYSTEM_PING.
net/icmp: Adds basic build framework to support IPPROTO_ICMP sockets.
