Suport Spring ParameterizedTypeReference for returnTypes of Workflow CallActivity()

[salaboy]

Expected Behavior

When calling a Workflow activity, we should support parameterized types for return types, as it is supported in Spring:

new ParameterizedTypeReference<List<OrderItem>>(){}

Actual Behavior

We only support Class<V> returnType;

default <V> Task<V> callActivity(String name, Object input, Class<V> returnType)
