Emit dropck normalization errors in borrowck

Borrowck generally assumes that any queries it runs for type checking will succeed, thinking that HIR typeck will have errored first if there was a problem. However as of #98641, dropck isn't run on HIR, so there's no direct guarantee that it doesn't error. While a type being well-formed might be expected to ensure that its fields are well-formed, this is not the case for types containing a type projection:

```rust
pub trait AuthUser {
    type Id;
}

pub trait AuthnBackend {
    type User: AuthUser;
}

pub struct AuthSession<Backend: AuthnBackend> {
    data: Option<<<Backend as AuthnBackend>::User as AuthUser>::Id>,
}

pub trait Authz: Sized {
    type AuthnBackend: AuthnBackend<User = Self>;
}

pub fn run_query<User: Authz>(auth: AuthSession<User::AuthnBackend>) {}
// ^ No User: AuthUser bound is required or inferred.
```

While improvements to trait solving might fix this in the future, for now we go for a pragmatic solution of emitting an error from borrowck (by rerunning dropck outside of a query) and making drop elaboration check if an error has been emitted previously before panicking for a failed normalization.
