Fix array-like methods on V4 sequences

We need to properly convert value type lists on assignment and we need
to add the "length" property to the own properties. Furthermore, the V4
sequence methods were confused about integer type ranges. We teach
them about qsizetype, properly range check everything, and drop the
artificial limitation to INT_MAX.
