bors af30656785 Auto merge of #14436 - lowr:patch/normalize-assoc-type-in-path-expr, r=HKalbasi 
Normalize associated types in paths in expressions

Part of #14393

When we resolve paths in expressions (either path expressions or paths in struct expressions), there's a need of projection normalization, which `TyLoweringContext` cannot do on its own. We've been properly applying normalization for paths in struct expressions without type anchor, but not for others:

```rust
enum E {
    S { v: i32 }
    Empty,
}

impl Foo for Bar {
    type Assoc = E;
    fn foo() {
        let _ = Self::Assoc::S { v: 42 };   // path in struct expr without type anchor; we already support this
        let _ = <Self>::Assoc::S { v: 42 }; // path in struct expr with type anchor; resolves with this PR
        let _ = Self::Assoc::Empty;         // path expr; resolves with this PR
    }
}
```

With this PR we correctly resolve the whole path, but we need some more tweaks in HIR and/or IDE layers to properly resolve a qualifier (prefix) of such paths and provide IDE features that are pointed out in #14393 to be currently broken.
