Mirrors the existing BluetoothLERawAdvertisementsResponse benchmarks for
the remaining proxy message families: ZWaveProxyFrame/ZWaveProxyRequest,
SerialProxyDataReceived/SerialProxyWriteRequest, and
InfraredRFReceiveEvent/InfraredRFTransmitRawTimingsRequest.
Adds minimal stub headers under tests/benchmarks/stubs/ for the
zwave_proxy, infrared, radio_frequency, and serial_proxy components so
api_connection.cpp compiles without dragging in their UART/RMT/BLE
hardware dependencies.
