fix: UnitClass and UnitRace now work for target, focus, party, and all units

Browse source 
Previously UnitClass() only returned the correct class for "player" and
returned "Unknown" for all other units (target, focus, party1-4, etc.).
UnitRace() had the same bug.

Now both functions read UNIT_FIELD_BYTES_0 from the entity's update
fields to resolve class (byte 1) and race (byte 0) for any unit. This
fixes unit frame addons, class-colored names, and race-based logic for
all unit IDs.

Also fix UnitRace to return 3 values (localized, English, raceId) to
match WoW's API signature — previously it only returned 1.
