logic: add storage transformation to merge anonymous types and the respective typedef

* moved storage related classes to data/storage folder
* implemented recording c++ unions as NODE_UNION instead of just using NODE_TYPE
* added transformation to merge anonymous classes/structs/enums/unions and typedef nodes
* added tests for this transformation
* added setting for enabling/disabling this transformation
