To disambiguate local types, we append a "·N" suffix to their name and then trim it off again when producing their runtime type descriptors. However, if a local type is generic, then we were further appending the type arguments after this suffix, and the code in types/fmt.go responsible for trimming didn't know to handle this. We could extend the types/fmt.go code to look for the "·N" suffix elsewhere in the type name, but this is risky because it could legitimately (albeit unlikely) appear in struct field tags. Instead, the most robust solution is to just change the mangling logic to keep the "·N" suffix at the end, where types/fmt.go can easily and reliably trim it. Note: the "·N" suffix is still visible within the type arguments list (e.g., the "·3" suffixes in nested.out), because we currently use the link strings in the type arguments list. Fixes #54456.
