Andreas Kling f7a1696087 LibJS: Add MarkedValueList and use it for argument passing
A MarkedValueList is basically a Vector<JS::Value> that registers with
the Heap and makes sure that the stored values don't get GC'd.

Before this change, we were unsafely keeping Vector<JS::Value> in some
places, which is out-of-reach for the live reference finding logic
since Vector puts its elements on the heap by default.

We now pass all the JavaScript tests even when running with "js -g",
which does a GC on every heap allocation.
