- Crash: There was a missing FScopeLock when reading the skeletal mesh imported bulk data this was crashing if we access the bulkdata in two different thread in same time.
- Deadlock: The reload package function is doing a TThreadSfeObjectIterator which deadlock if the inner code create a UObject. The skeletalmesh build can be running in another thread and can create UObject when building the morphtargets. The fix is to move the work outside of the iterator, the iteration now just store the UObject into a TArray and the work is execute in a for loop after the iteration.

###
This change attempts to merge the editor and the runtime version of bulk data, i.e. bulk data one and two.
The major difference between the two is the fact that the editor version supported element vice
serialization via inheritance. This has been complelety removed in the runtime version. In order
to mitigate this divergance a non-virtual base class has been extracted that forms the base
for the untyped and typed versions of bulk data.
The untyped version is only used in editor and will be deprecated. However this is a breaking change,
previously it was possible to inherit from FByteBulkData in editor builds.
Other differences between the two includes:
* IsBulkDataLoaded - returns true for bulk data 1 if an allocation has been made even if the size is zero
* StartStreaming - was removed in bulk data 2 and has been removed
* FlushAsyncLoading - bulk data 2 was busy waiting, now an event is used
All I/O related functionality has been extracted into BulkDataStreaming.cpp and is using
a FBulkDataChunkId that is either a package path or a package ID.This could potentially
be extended to contain a cache key in development builds to support loading from DDC, i.e derived
data references.

Add ShortestToGarbage option to deduplicate reference chains by the root reference & the first garbage object encountered.
Do not use the 'Visited' counter for the FGCObject referencer so that we can find multiple chains that terminate there since it handles many disparate types of reference.
When removing duplicate chains, if the chain root is the GC object referencer, use the previous object in the chain as a key instead.
Sort chains by length before deduplicating in shortest/longest mode.
Truncate GCObjectReferencer strings in case they overflow FName's capacity.

Requires base casses to handle recursion for script packages and for finding UClass::StaticClass().
The class of class is class, and the outer of the class UPackage is a UPackage.
