Merge branch 'HDRP/staging' of https://github.com/Unity-Technologies/ScriptableRenderPipeline into HDRP/staging

com.unity.render-pipelines.high-definition/CHANGELOG.md

 - When LightLayers is enabled, the AmbientOclusion is store in the GBuffer in deferred path allowing to avoid double occlusion with SSAO. In forward the double occlusion is now always avoided.
 - Added the possibility to add an override transform on the camera for volume interpolation
 - Added desired lux intensity and auto multiplier for HDRI sky
+- Added an option to disable light by type in the debug menu
 - Added gradient sky
 
 ### Fixed
