feat: Implement dummy PersistenceAdapter for TestInput

[ysak-y]

Description

Implement dummy PersistenceAdapter and set it when building dummyAttributesManager object that is used in TestInput class.

Motivation and Context

Sometimes I want to use TestInput class with my actual ControlManager for e2e test. But sometimes I can't use it because of lacking persistenceAdapter in TestInput. When my implementation tries to refer persistentAttributes in AttributesManager, it raises Cannot get PersistentAttributes without PersistenceManager because there is no persistenceAdapter in TestInput.

So I want to implement dummy persistence adapter class and introduce it to TestInput.

Testing

You can refer to and operate persistentAttributes in handler implementation when using TestInput as input of the Control.
