Panel2 の ColumnDefinition Width はサイズを固定したくないのでスターにする必要がありますが、実際のピクセル値がほしい場合は Panel2 の Grid から ActualWidth を取得してこないと難しいのではないかと思います。

また GridSplitter は右側にはみ出すことができるため、Panel1 の ColumnDefinition には MaxWidth の設定が必要です。

ファイルIOに関しては本題ではない認識なので実装を割愛しています。実際は設計にもよると思いますが、MVVM で製作しているならば Model で保存、読み込みの処理を行い、掲示した自分のコードの場合は Model.Panel1Width に初期値として渡してあげれば良いかと思います。
