Unfortunately, recreating the device fails on NV.

This is similar to dolphin emulator dolphin-emu/dolphin#12191 |

@FATCatAndroid12 Not really. My PR was meant to help debug the cause of device lost errors so they can be fixed later rather than handle them. |

The idea is to gracefully teardown and recreate the Vulkan device if this happens due to either emulator or driver bug.
Currently, we don't fully implement LostDevice/RestoreDevice for Vulkan (as called from Android task switching), as in reality we do keep around the same device. So we don't delete/recreate everything, just most things, and finding the last things might be tricky.
However I was able to get this working to some degree on Intel GPU on Windows. On NVIDIA, I can't seem to create a new device in the same process after I've crashed one.
So overall, this is a bit questionable. Might be better to try to root out the remaining causes of lost device, although it would be nice to have this as a safety net.
