GameSettings: Add INI files for Mario Kart Arcade GP 2.

INI files for both known regions of _Mario Kart Arcade GP 2_ (Triforce)
have been added to the `GameSettings` directory:

| Game ID | Region |    Revision Date    |
| ------- | ------ | ------------------- |
| GNLE82  | NTSC-U | 2007/02/07 02:47:24 |
| GNLJ82  | NTSC-J | 2007/02/06 20:29:25 |

The files contain Action Replay and Gecko cheat codes. Some of the cheat
codes have been sourced from the Internet; others have been developed by
the author of this change.

> [!IMPORTANT]
> Triforce games may have had multiple revisions for a given game region
> after the original release, and Dolphin cannot distinguish them at
> this time. Cheat codes are developed for one revision only, and cannot
> work with other revisions.
>
> For this reason, every cheat code name is provided with a prefix that
> states the revision date of the target game revision. It will be up to
> the user to enable the cheat codes for their correct game revision and
> region. The revision date for _Mario Kart Arcade GP 2_ games can be
> seen in the SegaBoot menu, under the **ENTER GAME TEST > OTHERS**
> screen.

> [!NOTE]
> Prior to issue #14470, the game ID for the NTSC-U region was
> incorrectly assigned the game ID of the NTSC-J region due to an issue
> in how the region flag in boot.id files was treated. This issue
> blocked the addition of the INI files until the issue was resolved (a
> region mismatch would cause fatal errors if cheat codes for the wrong
> version were enabled in Dolphin).

> [!CAUTION]
> There have been seen game dumps in the wild that, even though their
> real region is NTSC-U, the region flag in their `boot.id` file is
> `0x02` (NTSC-J), instead of `0x0E` (NTSC-U).
