Nick Khyl 03acab2639 cmd/cloner, cmd/viewer, util/codegen: add support for aliases of cloneable types ... We have several checked type assertions to *types.Named in both cmd/cloner and cmd/viewer. As Go 1.23 updates the go/types package to produce Alias type nodes for type aliases, these type assertions no longer work as expected unless the new behavior is disabled with gotypesalias=0. In this PR, we add codegen.NamedTypeOf(t types.Type), which functions like t.(*types.Named) but also unrolls type aliases. We then use it in place of type assertions in the cmd/cloner and cmd/viewer packages where appropriate. We also update type switches to include *types.Alias alongside *types.Named in relevant cases, remove *types.Struct cases when switching on types.Type.Underlying and update the tests with more cases where type aliases can be used.
