Add Function.prototype.toString tests for async generator functions (#955)

* Add Function.prototype.toString tests for many function forms
* Add non-const computed property name to Function.prototype.toString tests
* Split class method tests into class-expression and class-statement tests
* Add tests for unnamed function expression forms
* Add tests for async (generator) methods in class contexts
* Add test case for Function.prototype.toString on async arrow function
