Add with_internal_states option

[st0012]

Besides arguments, sometimes internal states will affect a method's result too. But currently print_calls doesn't contain such information. So in such cases, users still need to dig into the method to check internal states.

Sample output:

:update? # CartOperationsService::OperationSet
    from: /Users/st0012/projects/ticketsolve/app/services/cart_operations_service.rb:102
    states:
     @price: 10.0
    <= {args: [], block: nil}
    => true
