When looking at `TView` debug template only Element nodes were displayed as `TNode.Element` was used for both `RElement` and `RText`. Additionally no text was stored in `TNode.value`. The result was that the whole template could not be reconstructed. This refactoring creates `TNodeType.Text` and store the text value in `TNode.value`. The refactoring also changes `TNodeType` into flag-like structure make it more efficient to check many different types at once. PR Close #39233
