[JSC] Remove redundant arguments from [Supplemental] custom methods

[Kentaro Hara]

Since in JSC a callback of custom methods is non-static, we do not need to pass a pointer of an implementation object.

Before (JSTestInterface.cpp):
JSValue jsTestInterfaceSupplementalStr3(ExecState* exec, JSValue slotBase, const Identifier&)
{
    JSTestInterface* castedThis = static_cast<JSTestInterface*>(asObject(slotBase));
    TestInterface* impl = static_cast<TestInterface*>(castedThis->impl());
    return castedThis->supplementalStr3(impl, exec);
}

After (JSTestInterface.cpp):
JSValue jsTestInterfaceSupplementalStr3(ExecState* exec, JSValue slotBase, const Identifier&)
{
    JSTestInterface* castedThis = static_cast<JSTestInterface*>(asObject(slotBase));
     return castedThis->supplementalStr3(exec);  // JSTestInterface knows 'impl'.
}

We should also remove redundant arguments from JSDOMWindowWebSocketCustom.cpp and JSDOMWindowWebAudioCustom.cpp.
