[Bug] (Vulkan) Tomodachi Life: Living the Dream crashes when feeding Mii

[AbsentGhost]

Prerequisites

• I am confident that my issue has not been reported already in open OR closed issues.
• I am able to reliably reproduce the issue on the latest stable or canary version.
• I am not using an unofficial build (Flatpak, Emudeck, etc.).
• I am a silly goose and didn't read these boxes.
• I am a silly goose and DID read these boxes.

Description of the issue

!! To be clear, this is a Linux issue !!

I have not attempted to, nor am I able to successfully reproduce this issue on Windows or MacOS.

Summary

When attempting to feed a Mii character, the emulator tries to copy a texture that uses 8 components, but the GetFormat function in the Vulkan helper shader only knows how to handle fewer than 8, causing it to crash.

Reproduction steps

Emulator Settings:

• Launch latest .appimage version of Ryujinx/Ryubing Canary
• Attempt to replicate my GPU/drivers as best as possible
• Ensure Tomodachi Life launches using Vulkan
• Nothing else should really matter, I tried changing a bunch of settings but narrowed it down to Vulkan

In Game:

• Launch game
• Create first Mii
• After unlocking the shop/ability to feed Mii, feeding the Mii should work
• However, before unlocking the wishing fountain, attempting to feed the Mii should crash the game consistently.

Extra notes

• I'm sure this issue is exclusive to Vulkan as the issue went away after swapping to OpenGL.
• I am using default settings in Ryubing, no Vsync, no messing with CPU, etc.
• Only thing I changed was Vulkan to OpenGL
• I'm also using Wayland in case it's relevant (sometimes it's an issue).

Can confirm this happens to me on Windows too! Issue went away when I used an older version of Canary (1.3.341)
