[ES6][ES7] Drop Constructability of generator function
https://bugs.webkit.org/show_bug.cgi?id=152383

Reviewed by Saam Barati.

We drop the constructability of generator functions.
This functionality is already landed in ES 2016 draft[1].
And this simplifies the existing JSC's generator implementation;
dropping GeneratorThisMode flag.
