bootrom-tools: supply UniPro MID/PID values in nuttx2ffff based on --build flag

For ES3 boards we need to flash all firmware in the form of a TFTF inside an
FFFF, which must have the correct UniPro MID/PID and Ara VID/PID values for the
chip which loads it.  Begin adding this functionality to nuttx2ffff, based on a
hardcoded assignment of UniPro MID/PID values to --build values, where builds
can be associated with multiple chips.  Also build separate TFTF and FFFF
packages for each chip.

Testing Done: ES3 FFFF's generated containing correctly identified TFTF's
