Fix crash when serializing the return type of a generic call to Array.prototype.flat (#38904)
* Add declaration emit error and checking for circularly referential unions produced by recursive conditionals

* Allow indexed accesses to produce alias symbols on types

* Add test that still triggers the declaration emit error

* Fix spelling
