Add Top Level Auto Caller

[Werebunny]

Expected Behavior

Tester can use the auto passthrough using only declared methods on the top type.

Current Behavior

Tester will always call all methods on the type.

Possible Solution

Filter the methods.

Additional Information

For testing subclasses that have big base classes where the base behavior doesn't need to be included (or is problematic).

[Werebunny]

All methods should do this, also fixes rare hidden test host crash (something around MemberwiseClone I believe).
