Run cfg-stripping on generic parameters before invoking derive macros Fixes #75930 This changes the tokens seen by a proc-macro. However, ising a `#[cfg]` attribute on a generic paramter is unusual, and combining it with a proc-macro derive is probably even more unusual. I don't expect this to cause any breakage.
