Clean template/helper.go (#23922)

The first step of #23328

This PR cleans:

1. Dead function like `SubStr`
2. Unnecessary function like `UseHTTPS`, it should be provided by
`window.origin`
3. Duplicate function like `IsShowFullName`, there was already a
`DeafultShowFullName`

I have searched these removed functions globally, no use in code.
