[DXR] Black artifacts appear on metallic surfaces when Screen Space Reflection is used
How to reproduce:
1. Download and open the attached project named "hdrp10_issues"
2. Open the SampleScene
3. Observe one of the car wheels in the Game view
Expected result: No visual artifacts can be observed
Actual result: Flickering black artifacts can be observed inside the wheel near the shadow(Track_1263744_V1)
Reproducible with: 2020.2.0a20(10.0.0-preview.13, 10.0.0-preview.26)
Not reproducible with: 2020.1.1f1(9.0.0-preview.33)
Could not test with: 2018.4.26f1(DXR was not available yet), 2019.4.6f1(Shader graph used for the material breaks when downgraded to 8.x.x or below)
Workaround: Downgrading to 9.0.0-preview.33 and then upgrading back to 10.x.x seems to resolve this
Notes:
1. No artifacts can be observed if Editor is switched to D3D11 which disables DXR

Resolution Note:
The attached project had invalid normals for the affected model which caused the ray-traced reflection to return a bad result.
