remove DeterministicRenderingConfig (#12811)

# Objective

- Since #12453, `DeterministicRenderingConfig` doesn't do anything

## Solution

- Remove it

---

## Migration Guide

- Removed `DeterministicRenderingConfig`. There shouldn't be any z
fighting anymore in the rendering even without setting
`stable_sort_z_fighting`
