Tracking ticket for GHC 8.8.4

This is the template to be used to create release tracking tickets. Copy this into a new issue and fill in the TODOs. Those items marked with major-only can be ignored for minor releases.

This is the release checklist for the TODO milestone. See #16816 for the template that this was derived from.
