Add gRPC-based voice agent service for AGL

Introducing a gRPC-based voice agent service for Automotive Grade Linux
(AGL) that leverages GStreamer, Vosk, Snips, and RASA. It seamlessly
processes user voice commands, converting spoken words to text,
extracting intents, and performing actions via the Kuksa interface (WIP).
