[JSC] Remove some of IsoSubspaces for JSFunction subclasses
​https://bugs.webkit.org/show_bug.cgi?id=194177

Reviewed by Saam Barati.

JSGeneratorFunction, JSAsyncFunction, and JSAsyncGeneratorFunction do not add any fields / classInfo methods.
We can share the IsoSubspace for JSFunction.
