Introduce new phosphor-tiny distro feature

This will be used by recipes to minimize the debug objects
installed into the flash image.

See the poky-tiny wiki for reference:
    https://wiki.yoctoproject.org/wiki/Poky-Tiny

Future commits will utilize this new distro feature to
minimize flash image size.

Tested: Verified it built.
