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.

server: Serialize series type in SeriesModelSerializer

Because of a Swagger limitation (unknown cause), getStyle's description
is put at interface level instead of method. This approach is preferred
to not having a description that works.

This change mainly depends on core org.eclipse.tracecompass change [1]:
