Improve type checking and inference for Generators and Async Generators (#30790)
* Improve typing for Generators and Async Generators

* Add TReturn and TNext to Iterator, IterableIterator, etc.

* Update ts internal Iterator to be assignable from global Iterator

* Make 'done' optional in IteratorYieldResult

* Revert Iterable and IterableIterator to simpler versions plus other fixes

* Add additional inference tests

* Added additional tests

* PR cleanup and minor async iteration type fix

* Updated diagnostics message and added non-strict tests

* Fix expected arity of Iterator/AsyncIterator
