Add icon support to context menu items

- Updated `MainPage.xaml` to include an icon for the first menu item.
- Added `CreateIconElementFromIconPath` method in `Helpers.cs` to create a `BitmapIcon` from a path, with error handling.
- Introduced `CreateImage` method in `PJDelegator` to generate a `UIImage` from an icon path.
- Modified `PJCollectionViewHandler.windows.cs` to set icons for `WMenuFlyoutItem` using the new helper method.
