Remove legacy
unknwon/com package (#19298)
Follows: #19284 * The `CopyDir` is only used inside test code * Rewrite `ToSnakeCase` with more test cases * The `RedisCacher` only put strings into cache, here we use internal `toStr` to replace the legacy `ToStr` * The `UniqueQueue` can use string as ID directly, no need to call `ToStr`
