extra: Add debug config overlay.

Add debug config overlay to easily build debug images.

Usage: ./extra/build.sh <board> --debug

The build includes extra/debug.conf which enables:

- Debug mode with assertions and verbose output
- Debug-level logging (level 4)
- Stack overflow detection
- Thread monitoring
- Debug optimizations (-Og)
- Enable shell.
