J. Nick Koston ecfb302c72 [rp2040] Tune oversized lwIP defaults for ESPHome
Arduino-pico's lwIP defaults are tuned for general-purpose networking,
not IoT devices. This generates a custom lwipopts.h overlay using
#include_next to chain to the framework's original, then override
specific settings to match ESP32's lwIP tuning.

Saves ~12KB static RAM by reducing oversized buffer and pool defaults.

Tested on Pico W (CYW43 WiFi) and Wiznet W5500 (Ethernet) with
500-iteration concurrent connect/disconnect stress tests.
