build system: establish priority levels for CBFS file additions
Add files with fixed positions, then files with alignment requirements
and finally those that can reside everywhere to prevent the most obvious
collisions.
This isn't perfect yet (the "aligned" group may need some additional
sorting), but should avoid the worst instances ("free floating" files
allocating space required by fixed location files, for example).
