Add deprecated expand ratio methods to FormLayout (#12876)

FormLayout has never implemented expand ratios but does not
tell the developer about it either. Throwing an UnsupportedOperationException
would make this very clear but at the same time would break
existing applications which use the methods or which handle
AbstractOrderedLayouts in a generic way.
