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.
