OTF2: Create generic class representing a SystemTreeNode
Added a generic class representing system tree nodes. This class can be inherited by the different OTF2 analyzes that use the system architecture. With this class, some recurrent functions related to system tree nodes do not need to be duplicated in these analyzes. Also changed the callstack state provider so it makes use of this new class.
