add java.lang.reflect.Type to deserialize API

Describe the proposal

As discussed https://github.com/dapr/java-sdk/issues/293 , TypeRef<T> was added to support deserialization of generic types. However, instances of TypeRef<T> can only be statically (during compilation) created. There are occasions when generic types need to be dynamically created. I suggest adding the following method to deserialize API to support such cases. <T> T deserialize(byte[] data, java.lang.reflect.Type type) throws IOException

The default serializer uses java.lang.reflect.Type. See type.getType() in the implementation below. Is this what you need?

  public <T> T deserialize(byte[] content, TypeRef<T> type) throws IOException {
    return deserialize(content, OBJECT_MAPPER.constructType(type.getType()));
  }

Not what I want. I need the following api. <T> T deserialize(byte[] data, java.lang.reflect.Type type) throws IOException

Note that one cannot create an instance of TypeRef<T> from java.lang.reflect.Type dynamically.
