logic: add type information of variable decl to name hierarchy

* implemented this feature for both, CXX and Java
* adjusted tests to reflect these changes
* added NameElement and NameHierarchy to Java code
* created more specialized JavaDeclName classes: JavaFunctionDeclName and JavaVariableDeclName
* implemented recording static modifier for Java methods and variables
