Adds a parameter to `Toolkit.ThumbnailHelper.GetThumbnail` to retrieve the largest possible icon from the file. For most use cases, the normal icon size will be good for list items and page icons. But for details, you'll want to use the JUMBO icons, and to retrieve them, we need to get the icon from a different API. As a drive-by, I also have us fetching the highest-res app icon for UWP's rather than the lowest-res icon. Solves #38238 Screenshots: | before | after | | ------ | ----- | |  |  | |  |  |
