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. Signed-off-by: Damien George <damien@micropython.org>

Probably not needed anymore. That was there originally as a full lwIP configuration for ports if they wanted to use it, but none ever did, the ports all needed their own custom configuration (there are also |

Summary
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.
Testing
For each port built a board with lwIP enabled:
RPI_PICO_W,PYBD_SF6,TEENSY41,ARDUINO_PORTENTA_C33. Built both before and after the commit in this PR. Then compared the binary firmware. The only things that changed in the binary were (1) the git commit hash in the version string; (2) the ordering of some of the pins in themachine.Pin.boarddict (for some reason the order of these are not deterministic). So I could conclude that the lwIP config changes are a no-op.Edit: also built an stm32 board with PPP enabled and it builds.
