util/spd_tools: Add max ID check for auto-generated IDs to part_id_gen

Currently, the maximum part ID of 15 is enforced only for manually
assigned IDs. Also enforce it for automatically assigned IDs.

BUG=b:191776301
TEST=part_id_gen fails when the number of part IDs which would be
assigned is greater than MaxMemoryId.
