[HDRP] HDRI and Physically Based sky cause memory leaks when the sun is updated every frame
How to reproduce:
1. Open the attached "SkyRenderMemLeak" project
2. Open the "TestMemoryLeak" scene
3. Open the Profiler window
4. Enter Play mode
5. In the Hierarchy, select the SimWorld GameObject
6. In the Inspector, enable the "Update_sun" property and inspect the Profiler
Expected results: There is no significant decrease in performance or increase memory usage
Actual results: Performance decreases and memory usage increases significantly
Reproducible with: 2019.3.0f1, 2019.3.0f4 (HDRP 7.1.6), 2020.1.0a17 (HDRP 7.1.7)
Not reproducible with: 2019.3.0f1 (HDRP 7.1.5)
Note: With "Update_sun" enabled, a memory snapshot shows many "InScatteredRadianceTable" and "SkyboxCubemap" objects under Not Saved > RenderTexture

I'm also seeing the same issue in my game. I'm working around the issue by disabling any render volumes that affect the sky render. Leak began after updating from 2019.2.17f1 to 2019.3.0f6.
