Feature: Add support for assigning keyboard shortcut to shortcut files

### What feature or improvement do you think would benefit Files?

On Windows, shortcuts located within certain folders will be scanned and their designated hotkey specified within their metadata will be listened to, and such shortcuts will be ran once their hotkey is pressed.

One is able to fill such a field through the Windows Explorer, in the properties dialog of a shortcut.

This field is not present in the Files App properties dialog.

### Requirements

As this field corresponds to a combination of modifiers and a single key, as opposed to other fields which are typically text only, a new sub-kind of field would have to be implemented, wherein modifiers would be mapped to a string spelling their name.

1. Display the currently selected shortcut if one is set
2. Display edit button or icon upon which clicking will allow the user to change the shortcut
3. Display save button or icon to allow user to save the shortcut

### Comments

_No response_

Start by tracing the Files properties dialog for shortcut files and the existing shortcut metadata handling. Confirm how Windows represents the hotkey, then define the modifier/key field's edit and save flow. Done means the selected shortcut is displayed, can be edited and saved, and launches with its assigned hotkey.
