  2. net: sockets: Extend socket vtable 

    This commit extends socket vtable, allowing to redirect socket calls to
alternate implementations (e.g. TLS sockets).

  4. net: sockets: Rework poll to support ioctl helper commands 

    This commit reworks socket poll implementation to support multiple
socket implementations.

To achieve that, two ioctl poll helper requests were added:
ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll
implementation calls ioctl with these requests for each socket
requested in the fds table.

The first request is responsible for preparing k_poll_event objects
for specific socket. It can request to skip waiting in k_poll by
returning EALREADY through errno.

The latter request is responsible for processing outcome of k_poll for
each socket. It can request to retry the k_poll by returning EAGAIN
through errno.
