Frame time increase in HDRenderPipelineRenderCamera and DepthPrepass when using HDRP above 2020.3
Reproduction steps:
1. Open the “SampleScene” scene in the attached “Project_21_3_upgraded.zip“ project
2. Open Build Settings and enable “Development Build” and “Autoconnect Profiler”
3. Build And Run
4. Open Profile Analyzer and select the Compare mode
5. Load “Capture_20_3.pdata” for the first data set
6. Wait a few seconds for the Profiler to stabilize and Pull Data for the second data set
7. Set “Name Filter” to Any and input “HDRenderPipelineRenderCamera DeferredDepthPrepass ForwardDepthPrepass DepthPrepass“
8. Select “Main Thread” and “Render Thread”
9. Compare the HDRenderPipelineRenderCamera markers
10. Compare the DeferredDepthPrepass (21.3+) and ForwardDepthPrepass (21.3+) markers against the DepthPrepass (20.3) marker
Expected result: The markers add up to relatively the same frame times in both data sets
Actual result: Pulled data frame times are significantly higher (~10%)

Resolution Note:
There are many changes and addition done between two LTS versions of HDRP so it's expected to see difference in performance as features may have changed or been added. Because of that it's hard to do a reliable side by side comparison of two such versions.
We are doing regular passes of optimization so if anything obvious happened we should be able to fix it.
