feat(api): expose common types in the top-level ibis namespace (#9008)

Adds `Table`, `Column`, `Scalar`, `Value`, and `Deferred` to the
top-level `ibis` namespace. These are mostly useful for downstream users
consuming the ibis api (either type-annotating their code, or using
`isinstance` checks).

Fixes #8717.
