Add OpenKNX IDF component with TPUart integration

- Created CMakeLists.txt for the OpenKNX IDF component, ensuring dependencies on OpenKNX and TPUart submodules. - Implemented Arduino compatibility header for basic functions like millis, delay, pinMode, and digitalRead. - Developed EspIdfPlatform class for network interface management and multicast communication. - Added EtsMemoryLoader for loading ETS memory snapshots and managing associations. - Introduced TpuartUartInterface for UART communication with methods for reading, writing, and managing callbacks. - Implemented arduino_compat.cpp for Arduino-like functionality on ESP-IDF. - Created source files for platform and memory loader implementations. - Updated submodules for knx, knx_dali_gw, and tpuart.
