Bindings: Make item_value return an Optional<JS::Value>

This removes some ambiguity about what the return value should be if
the index is out of range.

Previously, we would sometimes return a JS null, and other times a JS
undefined.

It will also let us fold together the checks for whether an index is a
supported property index, followed by getting the value just afterwards.
