The Blueprint compiler is not consistent with UHT when generating DefaultToInstanced variables

UnrealHeaderTool and the Blueprint compiler generate inconsistent metadata for object reference variables whose underlying class type includes 'DefaultToInstanced' metadata.

UnrealHeaderTool-generated fields implicitly add 'EditInline' to the variable's metadata so that fields of this type can be instanced directly in the Property Editor at edit time. However, the Blueprint compiler does not currently match this behavior, so variables of this type added through the Blueprint class editor cannot be instanced directly in the same manner.

Workaround:
Define a native "wrapper" BlueprintType struct or class on the C++ side containing a variable of this type, and then add a variable of the native wrapper type on the Blueprint class side.

1. Open the attached (sample) project in the 5.3 editor.
2. Open DA_TestDataAsset.
3. Open the 'MyEffects' member element (index 0).
4. Note that only the "Wrapped Int Value" member can be inline-edited.
   Expected result: Both "Int Value" and "Wrapped Int Value" members should be inline-editable.
