    bitbake.conf: Use -Og in DEBUG_OPTIMIZATION
    
    -Og is for optimized debugging experience.
    this makes this consistent across different compilers especially gcc and
    clang, -O in clang is equal to -O2 where as in gcc its similar to -O1
    so it was not giving consistent debugging experience across compilers
