fix: add missing API bindings from discussion #8992 for Go and TypeScript

- Go tactic.go: add Goal.Depth(), Goal.Precision(), Goal.Translate(), Goal.ConvertModel()
- Go solver.go: add FuncEntry struct, FuncInterp.GetEntry/SetElse/AddEntry, Model.HasInterp
- TypeScript types.ts + high-level.ts: add Seq.map/mapi/foldl/foldli
