This lwIP configuration file has options that are common to all ports, and
the ports are updated to use this file. This change is a no-op, the lwIP
configuration remains the same for the four ports using this common file.
This reduces code duplication, keeps the ports in sync, and makes it easier
to update the configuration for all ports at once.

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.
