Add ESP32-S3 camera component selection and support (#1670)

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.
