BuildROMs: Move ROM exclusion logic into ROM include files

Browse Source 
- Plan is to avoid "#ifdef DONT_USE_INTERNAL_ROM" in simulator code
  and handle builtin or external files in SCP facilities
- Export ROM checksum value and source file path to allow for transparent
  dynamic ROM location at run time.
