Egor c2cf8e4fb1 perf: speed up local inference on shared GPU (#9968)
## Summary

Allows to disable UI animations to speed up local inference on shared
GPU setups. Gives 7-13% improvement

## Changes

- **What**: New setting under Appearance > General. Applies a CSS class
that disables all animations and transitions
- **Breaking**: None since it's opt in

I also considered auto-disabling animations only during generation on
shared GPU setups. We could detect that, lmk if you want it to be
implemented.

## Screenshots

/>

## How to reproduce:

- Run frontend & backend locally on a device with shared GPU
- Install the model: `cd models/checkpoints && curl -L -o
v1-5-pruned-emaonly-fp16.safetensors
"https://huggingface.co/Comfy-Org/stable-diffusion-v1-5-archive/resolve/main/v1-5-pruned-emao
  nly-fp16.safetensors"` (~2GB)
- Use this workflow: https://cloud.comfy.org/?share=4086706e0018 (also
