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- Removed outdated comments and code related to the previous camera implementation in the README file.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- Removed outdated camera configuration options from config.json to streamline the setup.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.
