This fix always initializes it to a valid pointer, but invalid handle, which is a state that is handled correctly in FPropertyHandleBase.

- Allow drag-and-drop behavior to be customized for a details widget row
- Cleanup PropertyEditorHelpers::MakePropertyReorderHandle (it was setting the enabled attribute which always ended up getting overwritten)
- Add drag-and-drop handler+op for UserDefinedStructureEditor to enable drag-and-drop reordering. Removed buttons for moving up/down.

CustomEditConditionValueChanged handlers are now postfixed with a call to FPropertyNode::InvalidateCachedState(), which causes the IsEditConst state to refresh.
Removed unnecessary code to access the PropertyEditor->IsEditConditionMet(), which is stored in EditConditionValue now.

FPropertyHandleImpl also no longer causes an infinite loop of deferred actions when a custom reset to default is set on a property row.

The details view now displays gridlines between rows, and now has 4 columns - edit condition, name, value, and reset/extensions.
Edit condition widgets are now created in SDetailSingleItemRow and are placed in their own fixed column on the left of the details view. FEditConditionParser is now in FPropertyNode rather FPropertyEditor, which allows access to it more broadly - notably in SDetailSingleItemRow.
The Reset to Default SWidget can no longer be replaced - the logic for it being visible and a handler for when it is pressed is still customizable. SPropertyEditorAsset no longer has a special slot for the reset to default widget.
All extension widgets are now placed in a resizable column on the right of the panel, including the Keyframe button.
FDetailColumnSizeData is now publicly exposed by IDetailsView, and is no longer passed around as much.
