[`unnecessary_literal_unwrap`]: Fix ICE on None.unwrap_or_default()

Fixes #11099
Fixes #11064

I'm running into #11099 (cc `@y21)` on my Rust codebase. Clippy ICEs on this code when evaluating the `unnecessary_literal_unwrap` lint:
```rust
fn main() {
    let val1: u8 = None.unwrap_or_default();
}
```

This fixes that ICE and adds an message specifically for that case:

```
error: used `unwrap_or_default()` on `None` value
  --> $DIR/unnecessary_literal_unwrap.rs:26:5
   |
LL |     None::<String>.unwrap_or_default();
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: remove the `None` and `unwrap_or_default()`: `String::default()`
```

This PR also fixes the same ICE with `None.unwrap_or_else` (by giving the generic error message for the lint in that case).
