feat: Add project support for the EDA course case team (#1758)

* Add EDA Education Board Configuration

- Add eda-tv-pro Board Configuration
- Add eda-robot-pro Board Configuration
- Add eda-super-bear Board Configuration

* docs(oscillator): Add file headers with copyright and license information

- Add comprehensive file headers to oscillator.cc and oscillator.h in eda-robot-pro board
- Add comprehensive file headers to oscillator.cc and oscillator.h in eda-super-bear board
- Include original author attribution (Juan Gonzalez-Gomez/Obijuan) and ESP32 port credit (txp666)
- Include GPL license notice and file descriptions for clarity and compliance

* fix: Move the eda* boards to the lceda-course-examples folder.

- Move eda-robot-pro, eda-super-bear, and eda-tv-pro boards to lceda-course-examples subdirectory
- Update CMakeLists.txt to set MANUFACTURER variable for each board configuration
