TMap property on AnimNode causes memory corruption

FastPath can't handle TMap (maybe any other container type too) in AnimGraph causes this crash.
FastPath copies TMap property to the AnimNode member property directly like MemCopy.
So two properties point the same address.
At garbage collection, The pointer will be released twice.

As a workaround, Wrapping TMap with struct works fine.
Because it's handled as ECopyType::StructProperty.

1. Build and open [Link Removed] with UE4.24
2. Open Contents/Mannequin/Character/Mesh/TestFNameMapABP
3. Repeat to compile and save it until engine crash( using "-stompmalloc" can trap it easily)
