[`box_default`]: Preserve required path segments

When encountering code such as:
```rs
Box::new(outer::Inner::default())
```
clippy would suggest replacing with `Box::<Inner>::default()`, dropping the `outer::` segment. This behavior is incorrect and that commit fixes it.

What it does is it checks the contents of the `Box::new` and, if it is of the form `A::B::default`, does a text replacement, inserting `A::B` in the `Box`'s quickfix generic list.
If the source does not match that pattern (including `Vec::from(..)` or other `T::new()` calls), we then fallback to the original code.

Fixes #11927
