Switch to `NET_SOCKET_REGISTER` mechanism over the offloaded API
registration.
Including the following fixes from the review:
* The fd returned by the socket accept call needs to be finalized,
similar to how it is done for socket creation.
* sl_RecvFrom() in TI SimpleLink Host driver does not support NULL
pointers for 'from' address and address length, and sl_SendTo() does
not ignore the destination address when in connection mode, so passing
NULL would cause a failure. These issues have been reported to TI
(CC3X20SDK-1970, CC3X20SDK-1971).
Let's use sl_Recv and sl_Send to implement recvfrom/sendto in the case
of NULL addresses.
* simplelink_poll() should not process negative file descriptors in the
fds array after sl_Selecti() returns. A negative fd value indicates
that the entry is invalid and should be ignored.

This offloads the getaddrinfo() socket operation to the
simplelink WiFi driver, via a socket_offload hook.
This was validated using http_get on cc3220sf_launchxl.
Also implements freeaddrinfo().

If the SimpleLink WiFi driver is configured, and socket offload
enabled, this revectors the Zephyr BSD socket APIs to the SimpleLink
WiFi host driver BSD socket APIs, providing a
direct offload of the TCP/IP stack to the CC3220SF network
coprocessor.
