feat: Enhance EtsDeviceRuntime constructor and multicast handling

- Updated EtsDeviceRuntime constructor to accept an optional tunnel_client_address parameter with a default value of 0.
- Modified EspIdfPlatform::setupMultiCast to use IPPROTO_UDP for socket creation and improved multicast interface selection based on the current IP address.
- Ensured that the multicast interface is set only if a valid local address is available.
- Adjusted the client address assignment in EtsDeviceRuntime to use the provided tunnel_client_address if valid, falling back to the default otherwise.
