CmdPal: Add metadata to items in the clipboard history (#42188)

## Summary of the Pull Request

This PR introduces the `IClipboardMetadataProvider` interface, which
inspects clipboard items and returns metadata plus optional actions.

Also this implementation updates changes how `DetailsLink` link is
handled through shell, to enable `file:` scheme to be handled
(`Hyperlink.NavigateUri` and `HyperlinkButton.NavigateUri` explicitly
blocks `file:` scheme, see
[here](https://learn.microsoft.com/en-us/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.hyperlinkbutton?view=windows-app-sdk-1.8)).

**Implemented providers:**
- `ImageMetadataProvider` — reports image dimensions, DPI, and byte
size.
- `TextFileSystemMetadataProvider` — recognizes text as a file-system
path and, if it exists, provides details about the target.
- `WebLinkMetadataProvider` — recognizes text as a URL and provides
link-related metadata.
- `TextMetadataProvider` — reports text statistics (e.g., character and
word counts).
