Subject: [PATCH] Refactor `fmt::Display` for TokenKind, LiteralKind, and
 NumericLiteralKind to use `fmt::Debug::fmt`.

Replaces manual match statements for format display fallback implementations with delegation to `fmt::Debug::fmt`, saving boilerplate and removing typo-prone large enums mappings in `compiler/syntax/src/token_kind.rs`.
