types: remove no longer used version gate

This is done to break the dependency of `sql/types` on `roachpb` (which
is a part of the effort to clean up the dependencies of `execgen`). This
commit brings the dependencies of `execgen` to a much more reasonable
set.

Although there is an ask in place to not remove this code even if it's
not used at the moment (so that we have the necessary infra in place
if/when the need arises), in order to keep the functionality we would
need to pull out `roachpb.Version` out of `roachpb`, and I don't want
to embark on that since we're in stability period.

Release note: None

Release justification: low risk change to clean up the dependencies.
