[HDRP] Crash on GfxDeviceD3D12::BuildTopLevelAccelerationStructure when changing Forced Screen Percentage

Package: Scriptable Render Pipeline HD

-

Steps to reproduce:
1. Create a new HDRP project or open the one attached by the user
2. Open the DXR + HDRP section of the HDRP Wizard (Window -> Render Pipeline -> HD Render Pipeline Wizard -> HDRP + DXR)
3. Make sure the project is HDRP + DXR ready (if not, press the "Fix all" button)
4. Select the HDRenderPipelineAsset in the Project Hierarchy
5. In Inspector find Dynamic Resolution
6. Check "Enable" and then "Force Screen Percentage"
7. Change the Forced Screen Percentage value

Reproducible with: HDRP 7.1.5 (2020.1.0a17), 7.1.6 (2019.3.0f4, 2020.1.0a17), 7.1.7 (2020.1.0a18)
Not reproducible with: HDRP 7.0.1 (2019.3.0b4), 7.1.1 (2019.3.0b4, 2019.3.0b12), 7.1.2 (2019.3.0b4, 2019.3.0b12)
Couldn't test HDRP 7.1.5 on 2019.3.0b4, 2019.3.0b12 due to UnauthorizedAccessException when trying to fix the HDRP + DXR issues in HDRP Wizard

Notes:
- Stacktraces seem to appear interchangeably
- After the crash, as long as the editor doesn't quit, it leaks memory
