Do not suggest use over extern crate w/ alias. 
This commit stops `unused_extern_crates` lints from occuring on `extern
crate` statements that alias the crate as the suggestion to change to a
`use` statement would result in the aliased name no longer being added
to the prelude, thereby causing compilation errors if other imports
expected this to be the case.

59183180f7 Auto merge of #56225 - alexreg:type_alias_enum_variants, r=petrochenkov 
Implement RFC 2338, "Type alias enum variants"

This PR implements [RFC 2338](https://github.com/rust-lang/rfcs/pull/2338), allowing one to write code like the following.

```rust
#![feature(type_alias_enum_variants)]

enum Foo {
    Bar(i32),
    Baz { i: i32 },
}

type Alias = Foo;

fn main() {
    let t = Alias::Bar(0);
    let t = Alias::Baz { i: 0 };
    match t {
        Alias::Bar(_i) => {}
        Alias::Baz { i: _i } => {}
    }
}
```

Since `Self` can be considered a type alias in this context, it also enables using `Self::Variant` as both a constructor and pattern.

Fixes issues #56199 and #56611.

N.B., after discussing the syntax for type arguments on enum variants with @petrochenkov and @eddyb (there are also a few comments on the [tracking issue](https://github.com/rust-lang/rust/issues/49683)), the consensus seems to be treat the syntax as follows, which ought to be backwards-compatible.

```rust
Option::<u8>::None; // OK
Option::None::<u8>; // OK, but lint in near future (hard error next edition?)
Alias::<u8>::None; // OK
Alias::None::<u8>; // Error
```

I do not know if this will need an FCP, but let's start one if so.

resolve: Fix another ICE in import validation

Imports are allowed to have ambiguous resolutions as long as all of them have same `Def`.
As it turned out, it's possible for different `Module`s to have same `Def` when `extern crate` items are involved.
