  [LLDB] Recognize `std::noop_coroutine()` in `std::coroutine_handle` pretty printer

With this commit, the `std::coroutine_handle` pretty printer now
recognizes `std::noop_coroutine()` handles. For noop coroutine handles,
we identify use the summary string `noop_coroutine` and we don't print
children

Instead of
```
(std::coroutine_handle<void>) $3 = coro frame = 0x555555559058 {
  resume = 0x00005555555564f0 (a.out`std::__1::coroutine_handle<std::__1::noop_coroutine_promise>::__noop_coroutine_frame_ty_::__dummy_resume_destroy_func() at noop_coroutine_handle.h:79)
  destroy = 0x00005555555564f0 (a.out`std::__1::coroutine_handle<std::__1::noop_coroutine_promise>::__noop_coroutine_frame_ty_::__dummy_resume_destroy_func() at noop_coroutine_handle.h:79)
}
```

we now print

```
(std::coroutine_handle<void>) $3 = noop_coroutine
```
