WebGPURenderer: Remove error-reporting code unrelated to this PR.

These changes belong to mrdoob#33418 and were bundled into this branch by mistake.

- Renderer.js: drop `onError` / `_onError` hook.
- WebGPUBackend.js: drop `device.onuncapturederror` → `renderer.onError` bridge.
- WebGPUPipelineUtils.js: revert to dev (removes pipeline-label error messages and `_reportShaderDiagnostics`).
