drivers: wifi: simplelink: Rework offloading mechanism

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.
