Associative container of GameplayAbilitySpecs + PredictionKeys --> FAbilityReplicatedDataCache. Basically, it holds replicated data on the ability system component that abilities access in their scripting. This was refactored from a normal TMap. This mainly servers to:
Return shared ptrs to the cached data so that callsites are not vulnerable to the underlying map shifting around (E.g invoking a replicated event ends the ability or activates a new one and causes memory to move, invalidating the pointer).
Data is cleared on ability end via Remove.
The FAbilityReplicatedDataCache instances are recycled rather than allocated each time via FreeData.
