zephyr: Replace broken shell_net_iface() with more general shell_exec().

Browse Source 
The zephyr function net_shell_cmd_iface() was removed in zephyr v1.14.0,
therefore the MicroPython zephyr port did not build with newer zephyr
versions when CONFIG_NET_SHELL=y. Replace with a more general
shell_exec() function that can execute any zephyr shell command. For
example:

>>> zephyr.shell_exec("net")

Subcommands:
  allocs     :Print network memory allocations.
  arp        :Print information about IPv4 ARP cache.
  conn       :Print information about network connections.
  dns        :Show how DNS is configured.
  events     :Monitor network management events.
  gptp       :Print information about gPTP support.
  iface      :Print information about network interfaces.
  ipv6       :Print information about IPv6 specific information and
              configuration.
  mem        :Print information about network memory usage.
  nbr        :Print neighbor information.
  ping       :Ping a network host.
  pkt        :net_pkt information.
  ppp        :PPP information.
  resume     :Resume a network interface
  route      :Show network route.
  stacks     :Show network stacks information.
  stats      :Show network statistics.
  suspend    :Suspend a network interface
  tcp        :Connect/send/close TCP connection.
  vlan       :Show VLAN information.
  websocket  :Print information about WebSocket connections.

>>> zephyr.shell_exec("kernel")

kernel - Kernel commands
Subcommands:
  cycles   :Kernel cycles.
  reboot   :Reboot.
  stacks   :List threads stack usage.
  threads  :List kernel threads.
  uptime   :Kernel uptime.
  version  :Kernel version.
