Cannot :nodoc: def_clone macro

[Blacksmoke16]

Bug Report

Somewhat related to #14039, the def_clone macro has a comment directly on the method generated by the macro. This makes it so you cannot customize the API docs for the generated method. My use case being wanting to throw a :nodoc: on it.

Easiest solution would be to remove the default comment, but could maybe do something with https://crystal-lang.org/reference/1.15/syntax_and_semantics/macros/index.html#merging-expansion-and-call-comments to only use it if there is not a doc comment on the macro call.
