LibJS: Make DeclarativeEnvironment store bindings in a Vector

Browse source 
The previous storage for DeclarativeEnvironment looked like this:

    HashMap<FlyString, Binding> m_bindings;

This patch changes that to:

    HashMap<FlyString, size_t> m_names;
    Vector<Binding> m_bindings;

The main goal here is to give each binding an index that can ultimately
be cached and used for optimized environment accesses.
