* Creates a new shortcut (.lnk) file. This shortcut will be recorded in
* a new shortcuts log file located in %PROGRAMDATA%\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38
* that is named after the currently running application and current user, eg:
* Firefox_user123_shortcuts.ini.
*
* For reasons that we haven't been able to pin down, these shortcuts get created with
* extra metadata on them (KnownFolderDataBlock, SpecialFolderDataBlock) that cause
* the Windows ShellLink classes to improperly read their target path with certain
* parameters. This causes any 32-bit programs that read the links (such as our
* installer and uninstaller) to think that 64-bit installs are located in the 32-bit
* Program Files directory.
* for some additional discussion of this.
*
* @param aBinary Target file of the shortcut.
* @param aArguments Arguments to set for the shortcut. May be empty.
* @param aDescription The description of the shortcut. The string used here
* shows up as the hover text of the shortcut in Explorer and on the
* Taskbar (if the shortcut is pinned there).
* @param aIconFile The file containing the desired icon for the shortcut. This
* can be the same file as aBinary.
* @param aIconIndex The index of the in aIconFile. Note that this is 0 based index
* that IShellLinkW requires, _not_ a Resource ID that is sometimes used
* for icons.
* @param aAppUserModelId The App User Model ID to set for the shortcut. This will
* affect which icon on the Taskbar the application groups with when first
* launched.
* @param aShortcutFolder The special Windows folder to create the shortcut in. One of:
* CommonStartMenu, StartMenu, PublicDesktop, Desktop, or QuickLaunch.
* @param aShortcutName The filename of the shortcut within aShortcutFolder.
* @return The full native path to the created shortcut.
*
* @throws NS_ERROR_INVALID_ARG if an invalid shortcut folder is passed
* @throws NS_ERROR_FILE_NOT_FOUND if the shortcut file or shortcuts log cannot be
* created or accessed
* @throws NS_ERROR_FAILURE for other types of failures
