[fb] Add default hard-coded font

Browse Source 
For the fb driver to have a font before loading from disk is available,
create a hard-coded font as a byte array.

To create this, added a new scripts/psf_to_cpp.py which also refactored
out much of scripts/parse_font.py into a new shared module
scripts/fontpsf.py.
