Improve TrashBinDialog functionality

- Use the main display grid control to display deleted books
- Added search functionality for deleted books. This required creating a temporary search index in the `InProgress` folder. The products grid control now uses an instance of `ISearchEngine` to filter its grid entries.  The main grid uses a singleton instance of `MainSearchEngine`, which merely wraps `SearchEngineCommands.Search()`.  The TrashBinDialogs use `TempSearchEngine`.
- Users can now batch select `Everyting` as well as `Audible Plus Books`

Avalonia:
  - Refactor main grid context menus to no longer require reflection
