Fixes #4305 - 'FileDialog` TreeView (#4306)

Browse Source 
* Partial fix - probably breaks stuff

Refactored `FileDialog.cs` by replacing `treeViewContainer` with `_treeView`, adjusting UI component positions, and adding style properties to `_tableView`. Improved user interaction with new event handlers and key bindings. Rearranged `base.Add` calls to reflect the updated UI hierarchy.

* Tweaked Dialog and FileDialog attribute handling

Removed setting of _tableView.Style.InvertSelectedCellFirstCharacter = true;

Commented out custom attribute handling in Dialog.cs for VisualRole.Normal and VisualRole.Focus, reverting to base method. Removed InvertSelectedCellFirstCharacter setting in FileDialog.cs.

* Add tree view toggle to FileDialog

Introduced a new `_btnTreeToggle` button in `FileDialog.cs` to manage the visibility of a tree view within the file dialog interface. Added a new localized string `fdTree` in `Strings.Designer.cs` and `Strings.resx` for UI elements related to the tree view. Adjusted the layout and visibility of the tree and table views to accommodate the toggle functionality. Implemented methods `ToggleTreeVisibility`, `SetTreeVisible`, and `GetTreeToggleText` to handle tree view visibility logic. Cleaned up code and comments for clarity.

* Update localization and test logic for FileDialog

Updated `fdSearchCaption` localization from "Enter search string" to "Find" in `Strings.Designer.cs` and `Strings.resx`. Modified `FileDialogFluentTests.cs` to reflect UI changes by updating button text and removing skip conditions. Adjusted `FileDialogTests.cs` to change `TextField` caption and commented out certain test logic related to path confirmation.

* Moved Search view to be inside the table view container for better usability.

Refactor FileDialog to use nullable reference types

Updated the `FileDialog` class to adopt nullable reference types for improved null safety, marking fields, properties, and methods as nullable where appropriate. Simplified UI component initialization, including repositioning `_tbFind` and `_spinnerView` into `_tableViewContainer` and assigning `Id` properties to `_tableViewContainer` and `_tableView`.

Refactored methods like `TryAcceptMulti` and `GetFocusedFiles` to handle nullability. Simplified `Task.Run` calls and removed unused code, such as the `GetTextField` method and `FileDialogPart` enum, in `FileDialogTests.cs`. Updated tests to directly access subviews using `Id` properties. Minor layout and property adjustments were made to improve maintainability.

* Refactor Dialog class and improve null safety

- Enabled nullable reference types in `Dialog.cs` for better null safety.
- Removed and reintroduced static configuration properties with `[ConfigurationProperty]` attributes for configurability.
- Refactored `Dialog` constructor to use `base.ShadowStyle` and improved button management with alignment logic.
- Updated `Canceled` property with a private backing field and debug assertions.
- Added null-forgiving operators (`!`) across the codebase for nullable reference type compatibility.
- Introduced new test cases to verify `Dialog` behavior, including modal mouse capture and `Canceled` property access.
- Refactored and modernized existing test cases for consistency and readability.
- Removed redundant test cases and performed general code cleanup.
- Improved code comments and debug assertions for clarity and robustness.

* Refactor DialogTests to replace null with empty array

Updated the `BeginButtonTestDialog` method call in `DialogTests.cs`
to replace the `null!` argument with an empty array `[]`. This
improves type safety and ensures explicit handling of the argument.
