Update ChibiOS lwip to 2.1.3

[networkfusion]

Description

Bumps LWIP to next minor version that includes a number of fixes. See: https://git.savannah.nongnu.org/cgit/lwip.git/log/?h=STABLE-2_1_3_RELEASE

Motivation and Context

This brings the version in line with that used on ESP32 devices.

Improves ability to run on certain networks (such as ubiquiti unifi).
Improves ability to add IPv6 support.

How Has This Been Tested?

Running this on an orgpal3 with the networkfusion orgpal3 demo which extensively uses networking has not shown up any issues. It is comfortably getting an IP and using MbedTLS to send data to AWS IoT.
