adjust TargetActivatedOrTriggeredAbility

TargetActivatedOrTriggeredAbility takes a FilterStackObject rather than a FilterActivatedOrTriggeredAbility, which is bad style. Looking at the code I suspect Adric, Lithoform Engine, Vantress Visions are bugged as a result (though before the #12220 rework, the bug was masked). The rest might be okay because they're checking characteristics of a source, not sure.

Also, FilterActivatedOrTriggeredAbility is missing its copy() override and thus not using its copy constructor.

Start by locating TargetActivatedOrTriggeredAbility and FilterActivatedOrTriggeredAbility, then review the #12220 rework and the handling of Adric, Lithoform Engine, and Vantress Visions. Check the related source-characteristic cases as well. Done means the ability uses the intended filter type, its copying behavior is covered, and the suspected affected cards behave correctly.
