Support both esp_video and esp32_camera (#1671)
* Update project version to 2.2.1 and refactor camera component handling - Incremented project version from 2.2.0 to 2.2.1 in CMakeLists.txt. - Removed legacy esp32_camera component and replaced it with esp_video for ESP32-S3 and ESP32-P4 boards. - Updated board implementations to utilize the new esp_video component, ensuring compatibility and improved functionality. - Cleaned up Kconfig options related to camera selection, streamlining the configuration process. - Enhanced camera initialization logic across various board files to support the new component structure. * Refactor camera handling in AtomS3R CAM/M12 EchoBase board - Replaced the legacy EspVideo component with the new Esp32Camera class for improved camera functionality. - Updated camera initialization logic to utilize a more structured configuration approach, enhancing clarity and maintainability. - Removed outdated comments and code related to the previous camera implementation in the README file. * Update camera configuration for atoms3r-cam-m12-echo-base - Removed outdated camera configuration options from config.json to streamline the setup. - Retained essential partition table configuration for improved clarity. * Enhance Esp32Camera functionality and memory management - Added esp_timer.h for improved timing functionality. - Streamlined camera initialization by removing redundant frame buffer setup and logging. - Improved memory allocation for JPEG encoding and added error handling for unsupported pixel formats. - Updated comments for clarity and consistency, ensuring better understanding of the code flow.
