Add Pin/Unpin Shortcuts Feature

[mohammadsyuhada]

Option to create a shortcut/pin to a regularly used tools/games/ports in the main menu.

For example, I frequently used the ⁨Music Player⁩ app from tool or ⁨Songo#5⁩ from ports. While i can directly access the ⁨Songo#5⁩ from ⁨Recently Played⁩ or the ⁨Game Switcher⁩, i cannot do the same for application from tools. With this feature, I can pin (or create shortcut) to it in the main menu. The button to be used is the ⁨Y⁩ button.

• Add ability to pin tools, games, and multi-disc directories to the main menu
• Press Y on an item to pin/unpin with confirmation dialog
• Shortcuts appear alphabetically sorted in the main menu
• No reboot required - menu refreshes instantly after pin/unpin
• Optional background image for pak. Place it in /Tools/.media/<Pak Name>/bg.png
