LibJS: Remove Object::is_array() in favor of Value::is_array() and RTTI

Browse source 
It's way too easy to get this wrong: for the IsArray abstract operation,
Value::is_array() needs to be called. Since we have RTTI, the virtual
Object::is_array() method is not needed anymore - if we need to know
whether something is *actually* a JS::Array (we currently check in more
cases than we should, I think) and not a Proxy with an Array target, we
should do that in a way that doesn't look like an abstract operation.
