[CL 16774971 by francis hurteau in ue5-main branch]
- 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

Implement fast path for FCoreRedirects::GetMatchingRedirects when looking for a single redirect type.
Saves ~18% of the time spent in FLinkerLoad::FixupImportMap, which is time sliced in a 5ms window in PIE.

#fix actually allow for 32-byte aligned UObject allocations, allocate by size and aligment rather than aligned size and added development/debug build verification of resulting mem adress

- 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.

~40x speedup for set property loading, 281ms -> 6.5ms, initial load time for Win64 Test client in an internal project
Slight refactor in preparation of more advanced container allocators and allocating all UObject property memory linearly after UObject itself

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.

Apply similar logic to functions that are missing their parent implementation
Only for UScriptStructs that are outered to a UClass (e.g. sparse class data) and only when that class is not regenerating on load

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.

* Added a function to RedirectCollector to ingest soft package references
* Push the harevest soft package references from save to the redirect collector on a succesful save
* Moved the processing of soft package reference associated with a package during cook to after that package has been saved

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
