feat: add support for W5500 SPI Ethernet in gateway

- Introduced configuration options for wired Ethernet support in Kconfig and sdkconfig.
- Implemented Ethernet initialization and event handling in GatewayNetworkService.
- Enhanced app_main to manage Ethernet alongside Wi-Fi.
- Updated GatewayRuntime to store Ethernet information.
- Modified CMakeLists and include files to accommodate new Ethernet dependencies.
- Ensured backward compatibility by allowing Ethernet initialization failures to be ignored.
