[Feature Request]auto gen swagger comment for handler

**Is your feature request related to a problem? Please describe.**

when using idl for generate code, we currently add some simple comments for each handler
https://github.com/cloudwego/hertz/blob/0d8b98bc8cf61c16866359e551959e962597d33f/cmd/hz/generator/handler.go#L247-L261

but we have fully information for this endpoint, e.g. http method, serializer type, url path, request params, response params, and we have full info for request struct and response struct, like which field is used in path/query/body. So we can add a flag for hz to control generating swagger style comment for each method.

previous relates issues #28, #538, #558, #692

**Describe the solution you'd like**

In HttpMethod.InitComment, generate swagger style comment for using https://github.com/hertz-contrib/swagger

**Describe alternatives you've considered**

maybe we could provider a template like layout and package for the swagger comments.
