cqlvalue: make conversion to time_03 test utils

Since some other version of time_03 might be supported in the future,
we cannot have multiple methods such as `as_date()` defined.

I don't think it's good idea to expose version specific methods
(e.g. `as_date_03()`) to the users. This is why we make them
test utilities only.
