ClothConfigNV is reset when reloading assets that had been saved with 4.24

The new config object is created with the same serialization name as the legacy one "ClothConfigNV", causing the legacy data to be reset prior to migration.

Replacing In UClothingAssetCommon::AddClothConfigs() the line:

UClothConfigBase* const ClothConfig = NewObject<UClothConfigBase>(this, ClothConfigClass, ClothConfigClass->GetFName(), RF_Transactional);

by:

UClothConfigBase* const ClothConfig = NewObject<UClothConfigBase>(this, ClothConfigClass, NAME_None, RF_Transactional);

seems to help but this might not be the best solution moving forward as we then lose the correct serialization name for all new asset files.

1. get the UE4.24's ContentExample project from EpicGamesLauncher 2.There is a skeletal mesh called Owen. Duplicate it and create an OwenTest.

1. Change the values in the cross-configuration of Owen_Coat and save it. For example, change the GravityScale to 3.

1. Quit the ContentExample project and covert it to 4.25.

1. Open ContentExample. If you look at OwenTest, you can see that GravityScale is set to 1, which is the default. If you look at OwenTest, GravityScale is now the default 1, or rather, all of the configuration values are the defaults.
