Fixes #158954

This fixes an invalid lifetime suggestion involving argument-position impl Trait.

rustc could insert the new lifetime before the impl Trait argument, producing invalid code like 'a, impl Clone. Now it introduces the lifetime on the function generics instead.

This only changes the diagnostic suggestion.

"Lifetime may not live enough"'s suggestion adds a lifetime (incorrectly) to an unrelated impl Trait argument
