scylla/src/lib.rs: Don't re-export whole scylla_cql::value

Other scylla_cql re-exports don't usually re-export whole modules, only
what is necessary for scylla crate public API. This commit does the same
for `scylla_cql::value` re-export. All public items apart from
deser_cql_value are re-exported.
