[V8] There is no XXXConstructor that requires a custom getter
https://bugs.webkit.org/show_bug.cgi?id=109667

Reviewed by Adam Barth.

Currently '[Custom] attribute XXXConstructor xxx' generates
XXXAttrGetter(). However, there is no XXXConstructor with [Custom].
In addition, it does make no sense to generate XXXAttrGetter() for such cases.
We can remove the logic from CodeGeneratorV8.pm.
