OARIS — Subsystem Id Attributes are unnecessary

Subsystem Ids are introduced in the DDS IDL PSM (by the tool PIM to PSM transformation). They are added to each topic type (generated from each interface method).
DDS Partitions are a more flexible mechanism for logically partitioning multiple publishers and subscribers for the same topic.
Note that this is an issue raised on the DDS IDL PSM, it does not affect the PIM. The PIM considers it to be a PSM concern as to how multiple actors for the subsystem role in particular are distiguished.

Remove subsystem id insertion from PSM generation

The DDS PSM generation inserts a subsystem_id attribute into each topic type. This functionality should be removed, resulting in IDL without subsystem_id attributes, simplifying the translation of the PIM to DDS. Note that this does not impact the PIM.
