Fix aspect ratio swapping in Pitfall: The Lost Expedition

Based on Billiard's recommendations in this discussion: https://discord.com/channels/521709831132807179/521711075721478145/1216164450936160417

I've tested a handful of menus, cutscenes, FMVs, and the first 10 minutes of gameplay. I still want to play past the final boss with this before publishing the PR because I know the post-credit loads have weird aspect ratio even on console.
Myself and another community member have played through the entire game, including minigames, w/o issue.

Just curious if this is a similar problem/solution to Star Wars: Rogue Squadron 2/3 having aspect ratio swapping as well. I set Dolphin to Forced 4:3 and yet it still does vert- zoom in widescreen for cutscenes.

If forcing AR doesn't work around the problem it sounds unrelated.

Rogue Squadron uses the VI registers to put letterboxes on its cutscenes, and Dolphin only consides the active image area for calulating the optimal output resolution to resize to within the render window. So this is technically by design. One would have to define a sub-area within the render window that may be resized into to 'fix' that.
