fix(swift): keep nested types with undecoded identifiers unclassified

classifySwiftSymbol stopped at the first identifier it could not decode and
kept the enclosing nominal's category. A nested type named by a punycode or
word-substituted identifier (`0...`) inside a struct was therefore filed as a
struct, so analyze_swift_types reported nested enums and classes under
structs and dropped them from a classes filter and from unclassified. Such
an identifier may name a type of any kind, so the category is now unknown.

Fixes #5553
