[SharedCache] Limit sections being added in SharedCache::InitializeHeader to the regions being loaded

The logic before would default to adding a section unless it was from a region in the `regionsToLoad` argument and its header had already been initialized. However if a user does `Load Section by Address` then there's only one region in `regionsToLoad`. All sections not in that region would be automatically added, even if they had already been or the user hadn't requested them to be loaded.
