lwIP was recently updated in a89ac9e24a
to STABLE-2_2_0_RELEASE, and this introduced a change in the configuration
variable `DHCP_DOES_ARP_CHECK`, renaming it to `LWIP_DHCP_DOES_ACD_CHECK`.
This commit fixes the ports lwIP settings to use the new configuration
option.
Without this option, connecting to a WiFi access-point takes about 12.5
seconds. With this option (ie disabling DHCP ARP checks) connecting takes
about 4 seconds.
Tested on an RPI_PICO_W and PYBD_SF2.

This allows enabling lwIP debugging output. For example, to enable PPP
debugging add the following to `mpconfigboard.h`:
#define LWIP_DEBUG 1
#define PPP_DEBUG LWIP_DBG_ON

This patch allows to use lwIP as the implementation of the usocket module,
instead of the existing socket-multiplexer that delegates the entire TCP/IP
layer to the NIC itself.
This is disabled by default, and enabled by defining MICROPY_PY_LWIP to 1.
When enabled, the lwIP TCP/IP stack will be included in the build with
default settings for memory usage and performance (see
lwip_inc/lwipopts.h). It is then up to a particular NIC to register itself
with lwIP using the standard lwIP netif API.
