I'm updating ghc-tcplugins-extra, ghc-typelits-extra, ghc-typelits-natnormalise and ghc-typelits-knownnat based on these MRs, in order to provide full GHC 9.12 support, specifically to account for the change in the type of mkUnivCo to take [Coercion] (rather than DCoVarSet) for evidence the UnivCo depends on, and taking into account GHC #25394 to use ctEvCoercion rather than ctEvId.

See head.hackage !389. I'll ping you when that is ready and passes CI.

The patches have landed in head.hackage and should allow compilation with both GHC 9.12 and the current GHC head (the latest commit with relevant changes to the tcplugin API was 0225249a).

@christiaanb any movement on this?
