lola: Performance improvements for Service/Event[Data]Control#218
Conversation
This commit splits up ServiceDataControl, EventDataControl and EventControl into a data class (ServiceDataControl, EventDataControl and EventControl) which contains the data that is placed in shared memory and behaviour "view" classes (ServiceDataControlLocalView, EventDataControlLocalView and EventControlLocalView) which contain behaviour for interacting with the data via process local raw pointers which avoid performance overhead of interacting with data directly in shared memory (due to performance overhead of dealing with OffsetPtrs).
Since we always create a QM EventDataControl, we pass it into the composite by reference instead of by pointer to avoid doing nullptr checks within the composite (and for clearer semantics).
We previously introduced these classes to avoid additional bounds checking done when indexing into a DynamicArray in shared memory. Since we now are using the local views into shared memory, we no longer need this optimisation and can revert to simply accessing slots using their indices.
