- Avoid redundant iterations and processing of UPackages by implementing a listener instead
- Process many packages asynchronously (not just one) by keeping them in memory longer and finishing them later
- Make the ddc fill job wait for async tasks properly
- Fix texture always being single threaded by allowing async at all time for ddc fill jobs
- Avoid calling IsCachedCookedPlatformDataLoaded too often on objects still being compiled
- Use a more sensible max memory usage in WorldPartitionHelpers to avoid calling the GC too often
- 30m16s to 7m44s when running -run=DerivedDataCache -fill -map=P_Construct_WP -mapsonly -projectonly with hot cache
- 2h30m to 1h11s when running -run=DerivedDataCache -fill -map=P_Construct_WP -mapsonly -projectonly with cold cache

- Fixed tracing of UObject names and function names (UObject::CallFunction, FScopeCycleCounterUObject) when "stat named events" toggle is enabled (-statnamedevents, "stat NamedEvents" console command).
- Added FCpuProfilerTrace::OutputBeginDynamicEvent(const FName), in addition to existing API that receives const ANSICHAR* or const TCHAR*. It uses a separate DynamicFNameScopeNamesMap.

Fixed issue where changing a function signature in an interface wouldn't update nodes in a blueprint.
Changed the API of the deferred registry to be more inline with UE coding standards.

Add an enum value for transient package flags and clear them all on load from PackageFileSummary in addition to the current clearing on save, so that newly-marked transient flags that were previously saved out can still avoid being set when loading.

Add separate stack entries instead of inserting elements in one single array to minimize mem copying.
Minimize processing of non matching properties.
Do expensive IsA-checks only once per property.
Use TInlineAllocator to reduce allocations.
Fix broken GetPropertyChain feature.
Iterator Tests:
Extend test with recursion.
Add test without recursion.
Add test for SkipRecursiveProperty feature.
Add test for previously broken GetPropertyChain feature.
Impact on TPropertyValueIterator in EngineTest on Win64:
~2X speedup for TPropertyValueIterator<T> on UEngineTestPropertiesObject for any T != FProperty, less when actually iterating all properties
Impact on Garbage Collection Reachability Analysis for a big internal project on a slower platform running reachability analysis in parallel in 4 task queues:
~130 ms => ~005 ms for UClass::AddReferencedObjects (TPropertyValueIterator<FObjectProperty>) for the worst case UAnimBlueprintGeneratedClass
~150 ms => ~035 ms total wall time
~300 ms => ~130 ms total thread time
Impact on Garbage Collection Reachability Analysis for a big internal project on a faster platform running reachability analysis in parallel in 7 task queues:

- Added type-safe overloads of GetInterface/SetInterface on TScriptInterface.
- Added GetTypeHash to FScriptInterface.
- Cleaned-up operator= overloads with non-standard return types.
- Ensure that FScriptInterface is always constructed with both an object and interface argument specified.

This appears to be a really old holdover from early UE4 development. It was originally introduced in CL 1258792 to satisfy a lingering Engine dependency. However, that dependency was eventually removed in CL 3119255, which this change probably should've been lumped with.

Mostly casting directly to the correct type but caught a few bugs in selected types that are now fixed)
Also made such conversions warnings within the Chaos and ChaosCore modules, may promote to error once we're sure it's buliding fine.
