b52a7fc3ea Exclude JSDoc @extends from 'super()' checks (#29308) 
* Exclude JSDoc @extends from 'super()' checks

This fixes a similar problem as #29244 where JSDoc `@extends`

* fix check 'super can only be referenced in a derived class'

7a2b2cebbf Do not emit code for @extends tags in JS. (#29244) 
When transpiling JavaScript, TS3.1+ emits `@extends` tags as code. E.g.

    /** @extends {SuperClass} */
    class SubClass {}

Causes an ES5 emit that references SuperClass:

    /**
    * @extends {SomeBase}
    */
    var SubClass = /** @class */ (function (_super) {
        __extends(SubClass, _super);
        function SubClass() {
            return _super !== null && _super.apply(this, arguments) || this;
        }
        return SubClass;
    }(SomeBase));

Note the literal references to `SomeBase`.

This appears to be an accidental effect of 0f55566cf4. It refactored
`getEffectiveBaseTypeNode` for type checking, but missed an instance
where it is also used for emit logic. This change fixes the problem by
specifically getting the heritage clauses directly off the AST.
