Fix validations nested under a `given`

Multi-param and default validators, all of which implemented their
own `validate!` method, were not respecting the `given` dependency
as expected. This change copies the check into all those validators.

The bug was likely introduced by #1625, which required that the
dependency check be moved out of the scope itself and into the
validators. Rolling back that change would require fundamentally
re-architecting how array parameters are validated (possibly with
a new kind of scope).
