Esteban Küber 17a6ae2df3 Detect object safety errors when assoc type is missing
When an associated type with GATs isn't specified in a `dyn Trait`, emit
an object safety error instead of only complaining about the missing
associated type, as it will lead the user down a path of three different
errors before letting them know that what they were trying to do is
impossible to begin with.

Fix #103155.

// Test that a partially specified trait object with unspecified associated
// type does not type-check.
trait Foo {
type A;
fn dummy(&self) { }
}
fn bar(x: &dyn Foo) {}
//~^ ERROR the associated type `A` in `Foo` must be specified
pub fn main() {}
