PerfMonComps: Refactor the PerfMonMT measurements/data and clean things up a little bit

Although there seems to be a lot of changes in this MR the core functionality shouldn't actually change. We split the single Measurement/MeasurementData into dedicated structs. We now have two measurements: ComponentMeasurement and SnapshotMeasurement, and three data structs to hold these: ComponentData, EventLevelData, and SnapshotData. This way, we can unify the interface a little bit (i.e. no ad-hoc fnc_component, fnc_snapshot etc. anymore). While at it, I also tried to unify the naming conventions a bit but that's not completely done yet.

Additionally, we now also store the component-level wall-time measurements in the JSON that were previously excluded.
