DepthStencilState::depth_write_enabled == false && RenderPassDepthStencilAttachment::depth_ops.is_some() is not caught by validation

[CurryPseudo]

Description

let pipeline = device.create_render_pipeline(&wgpu::RenderPipelineDescriptor {
    depth_stencil: Some(wgpu::DepthStencilState {
        depth_write_enabled: false,
        ..
    }),
    ..
});

let mut pass = encoder.begin_render_pass(&wgpu::RenderPassDescriptor {
    depth_stencil_attachment: Some(wgpu::RenderPassDepthStencilAttachment {
        depth_ops: Some(&wgpu::Operations {
            load: wgpu::LoadOp::Load,
            store: false
        }),
        ..
    }),
    ..
});

Refer to https://gpuweb.github.io/gpuweb/#abstract-opdef-gpurenderpassdepthstencilattachment-gpurenderpassdepthstencilattachment-valid-usage:

• If format has a depth aspect and this.depthReadOnly is not true:
  • this.depthLoadOp must be provided.
  • this.depthStoreOp must be provided.
• Otherwise:
  • this.depthLoadOp must not be provided.
  • this.depthStoreOp must not be provided.

I expect getting a error from validation, but the depth buffer is discarded instead.
