don't throw classNameTDZError if referenced identifier is within a TypeAnnotation (#9190)

fix #9189

Obviously this code is intended to throw an error if someone tries to reference a class before it's defined, like:
```js
class Foo {
  someField = Foo;
}
```
But there's no problem with referencing the class in a type annotation before it's defined, and this is often necessary for tree structures:
```js
class Foo {
  [someSymbol]: Foo;
}
```
