Add support for "LexicalUUIDType".

Support it by treating it the same as UUIDType.

AFAIK originally there was LexicalUUIDType and TimeUUIDType. Lexical did
simple byte-wise comparison, where Time sorted using the UUID's time
value. UUIDType was added as a convenience type (CASSANDRA-2233) which
compares using the time value for time UUIDs, else byte-wise.
LexicalUUIDType was deprecated but not removed. We still have some
schema around explicitly using the LexicalUUIDType comparator.
