Improve template helper functions: string/slice (#24266)
Follow #23328 The improvements: 1. The `contains` functions are covered by tests 2. The inconsistent behavior of `containGeneric` is replaced by `StringUtils.Contains` and `SliceUtils.Contains` 3. In the future we can move more help functions into XxxUtils to simplify the `helper.go` and reduce unnecessary global functions. FAQ: 1. Why it's called `StringUtils.Contains` but not `strings.Contains` like Golang? Because our `StringUtils` is not Golang's `strings` package. There will be our own string functions. --------- Co-authored-by: silverwind <me@silverwind.io>pull/24230/head
