Rollup merge of #114029 - Enselic:clone-doc, r=scottmcm
Explain more clearly why `fn() -> T` can't be `#[derive(Clone)]`
Closes #73480
The derived impls were generated with `rustc -Z unpretty=expanded main.rs` and the raw output is:
```rust
struct Generate<T>(fn() -> T);
#[automatically_derived]
impl<T: ::core::marker::Copy> ::core::marker::Copy for Generate<T> { }
#[automatically_derived]
impl<T: ::core::clone::Clone> ::core::clone::Clone for Generate<T> {
#[inline]
fn clone(&self) -> Generate<T> {
Generate(::core::clone::Clone::clone(&self.0))
}
}
```
