Make LeafNode property nullable and return null when the binding expression
has no nodes (e.g., when using a constant source with a converter but no path).
This fixes an ArgumentOutOfRangeException that occurred when accessing
LeafNode or Description properties on such bindings.
Fixes#20441

* Fixed Selector.ValidateNestingSelector not calling overrides when iterating up through parent selectors
Changed ValidateNestingSelector to call recursively, walking up

exception.
