arch/x86: document CAR symbols and expose them in symbols.h
Attempt to better document the symbol usage in car.ld for
cache-as-ram usage. Additionally, add _car_region_[start|end]
that completely covers the entire cache-as-ram region. The
_car_data_[start|end] symbols were renamed to
_car_relocatable_data_[start|end] in the hopes of making it
clearer that objects within there move. Lastly, all these
symbols were added to arch/symbols.h.
