Vulkan: Avoid internal hash collision related to pipeline lookup
This fixes a bug where, under very rare circumstances, draw operations would render with the wrong parameters
Seen in Minecraft where the block highlighting lines would render as broken triangles, other games are possibly affected as well
Vulkan: Optimized data uploads to GPU
On systems with unified memory (integrated GPUs) we will use cached shared memory which has very low overhead
Data uploads are generally not a bottleneck in Cemu but this optimization might still help with performance on low-end systems
OpenGL/Vulkan: Fixed a regression from 1.25.3 where textures would show incorrectly or garbled
UI: The graphic pack preset selection is now more robust and consistent
Previously it was possible that the active presets would differ from the ones shown as active in the UI
UI: Fixed an issue in the texture cache viewer window where the overwrite resolution column would not show the correct value
