resolve: disallow label use through closure/async
This commit modifies resolve to disallow `break`/`continue` to labels
through closures or async blocks. This doesn't make sense and should
have been prohibited anyway.

fn main() {
// This used to ICE during liveness check because `target_id` passed to
// `propagate_through_expr` would be the closure and not the `loop`, which wouldn't be found in
// `self.break_ln`. (#62480)
'a: {
|| break 'a
//~^ ERROR use of unreachable label `'a`
//~| ERROR `break` inside of a closure
