i18n(pricing-coefficients): wrap BODY_TYPES/TRANSMISSION_TYPES CheckboxList options

The two CheckboxList options passed raw Vehicle::BODY_TYPES and
Vehicle::TRANSMISSION_TYPES arrays — now they run through I18n::opts()
so the RO values translate at display. +6 translations for the enum
values that weren't yet in dict (Crossover, Pickup, Minivan, DSG,
DCT, AMT).
