alexis matte 6fb8917a56 Fix a lock issue in CopyStructure, bulkdata are not playing well with thread so I prefer not using them for such small amount of editor data.
Removing them remove the following debug assert in LinkerLoad.h that happen when we copy FSkeletalMeshLODModel structure.

checkSlow(FPlatformTLS::GetCurrentThreadId() == OwnerThread);

It should also prevent a crash with file handle since we cannot lock two different bulk data in separate thread if the two bulk data are store in the same package since they will share a file handle
