Provide suggestion when trying to use method on numeric literal

New output:

```
error[E0688]: can't call method `powi` on ambiguous numeric type `{float}`
  --> $DIR/method-on-ambiguous-numeric-type.rs:12:17
   |
12 |     let x = 2.0.powi(2);
   |                 ^^^^
help: you must specify a concrete type for this numeric value, like `f32`
   |
12 |     let x = 2.0_f32.powi(2);
   |             ^^^^^^^
```

Previous output:

```
error[E0599]: no method named `powi` found for type `{float}` in the current scope
  --> src/main.rs:12:17
   |
12 |     let x = 2.0.powi(2);
   |                 ^^^^
   |
   = help: items from traits can only be used if the trait is in scope
help: the following trait is implemented but not in scope, perhaps add a `use` for it:
   |
11 | use core::num::Float;
   |
```

Fix #40985.
