HDRP Cluster artifacts when having more than 100 lights

-

*Steps to reproduce:*
# Download this project: [https://drive.google.com/file/d/1P1hNzK_9Pw8_E-GKs1liGAH9LWd-cdUn/view?usp=sharing]
# Open it with latest Unity on Windows or Mac
# Set the resolution to 4K
# Make sure you have all the Point Lights enabled in your scene
# Notice Clusters are flickering all over the GameView (c.f the gif below)

The bug has been there for a long time. Disabling many Point Lights makes it disappear, the same if you switch to a lower resolution. It seems related to the [lightlistbuild-clustered.compute|https://github.cds.internal.unity3d.com/unity/unity/pull/30926/files#diff-8c3d68eb892d88c27aeea446d9bec34f7ca8a53007334ec6cdbf681736b68323].
