feat: Create OpenTuna installer page

This commit introduces the initial OpenTuna installer page. The main menu now has an "Install OpenTuna" option that navigates to this new page.

The OpenTuna installer page currently performs the following actions:
- Detects and displays the PS2's ROM version.
- Handles memory card selection, prompting the user if multiple cards are inserted.
- Performs a free space check on the selected memory card.
