- Removed lambdas and TFunctions from FArchiveAsync (this was the culprit of the regression)
- Added THREADSAFE_UOBJECTS to easily disable UObject multithreading safety and potential overhead (not that it even exists)
- Moved a few functions so that they're not called too often (they come up in profiles)
