[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

This is not fixed. I'm still experiencing memory leaks in 2019.10, HDRP 7.3.1.

This is NOT fixed in 2019.3.1f7 HDRP 7.1.8
It starts happening if you move your physical lighting every frame (day\night cycle) and open one more editor viewport or select material\camera in inspector .

Still failing in 2019.3.2f1 HDRP 7.1.8
It makes our game Unplayable and the Editor unusable. We are due to release in the very near future, but cannot with this Bug.
We cannot upgrade to 7.2.0 where it is supposedly fixed (although not seeing any evidence of that in our test upgrades).
We need a fix or a workaround ASAP because right now we're supposedly using 15GB of VRAM for no real reason.

This is a huge problem for us. It also compromises our next milestone.

Need to RR the editor every 30-60 mins because of this. According to the profiler they end up taking 12GB+ and everything that has to do with RenderTextures starts misbehaving. Getting a lot of errors:
D3D11: Failed to create render texture primary RTV (error 0x887c0003)
D3D11: Failed to create render texture secondary RTV (error 0x887c0003)
