Invalid `type annotations needed` suggestion that leads to E0632

[nbdd0121]

This code produces invalid suggestion:

fn foo(x: impl Clone) {}
fn gen<T>() -> T { todo!() }

fn main() {
    foo(gen());
}

error[E0283]: type annotations needed
 --> src/main.rs:5:5
  |
1 | fn foo(x: impl Clone) {}
  |                ----- required by this bound in `foo`
...
5 |     foo(gen());
  |     ^^^ cannot infer type for type parameter `impl Clone` declared on the function `foo`
  |
  = note: cannot satisfy `_: Clone`
help: consider specifying the type argument in the function call
  |
5 |     foo::<impl Clone>(gen());
  |        ^^^^^^^^^^^^^^

Also this code:

fn foo<const N: usize>(x: impl Clone) {}
fn gen<T>() -> T { todo!() }

fn main() {
    foo(gen());
}

error[E0283]: type annotations needed
 --> src/main.rs:5:5
  |
1 | fn foo<const N: usize>(x: impl Clone) {}
  |                                ----- required by this bound in `foo`
...
5 |     foo(gen());
  |     ^^^ cannot infer type for type parameter `impl Clone` declared on the function `foo`
  |
  = note: cannot satisfy `_: Clone`
help: consider specifying the type arguments in the function call
  |
5 |     foo::<N, impl Clone>(gen());
  |        ^^^^^^^^^^^^^^^^^

None of them produce valid suggestion, as what it suggests will produce error[E0632]: cannot provide explicit generic arguments when impl Trait is used in argument position.

Related to #83606.
