Detailed Description

Helper class to lock the lwIP TCPIP core when making lwIP API calls from non-TCPIP threads.

This is needed on multi-threaded platforms (ESP32) when CONFIG_LWIP_TCPIP_CORE_LOCKING is enabled, and on RP2040 when CYW43 WiFi is active (cyw43_arch_lwip_begin/end).

On platforms without lwIP core locking (ESP8266, LibreTiny, Zephyr), this is a no-op defined inline so the compiler can eliminate all call overhead.
