LwIPLock was introduced for RP2040 WiFi in #14679 to prevent race conditions between lwip callbacks and the main loop. However, on platforms without lwIP core locking (ESP8266, LibreTiny, Zephyr, RP2040 without WiFi), the constructor/destructor were empty stubs in .cpp files that the compiler could not see through, generating unnecessary function calls at every call site. Move the no-op implementation inline into helpers.h so the compiler can eliminate all LwIPLock overhead on these platforms. ESP32 and RP2040+WiFi retain their out-of-line implementations with real locking.
