This is purely refactoring in preparation for allowing print documents to have a set of cache domains which is different to the global set. The free functions DomainsAreActive and RequestDomainsIfInactive are turned into methods on DocAccessibleParent, and a new EffectiveCacheDomains accessor is added on both DocAccessible and DocAccessibleParent. The original DomainsAreActive free function remains because it's still required by PlatformShouldTrackFocusedAccLocation on Mac, and passing a DocAccessibleParent to that is awkward.
