Introduces a new esp32s3_camera implementation for ESP32-S3 boards using the esp_camera component, with conditional compilation and Kconfig options to select between esp_camera and esp_video. Updates board initialization code and config files to use the new camera class where appropriate, and adjusts build system and dependencies to support both camera components on ESP32-S3 and ESP32-P4 targets.
Added camera-related sdkconfig options to esp32s3-korvo2-v3 and kevin-sp-v4-dev config.json files. Updated esp32s3_korvo2_v3_board.cc to implement button actions for WiFi config and chat state toggling. Refactored kevin-sp-v4_board.cc to unify I2C bus usage for codec and camera, and adjusted SCCB initialization logic.
