LibJS: Add length parameter to Array::create()

This is now a bit closer to the spec's 10.4.2.2 ArrayCreate - it will
throw a RangeError if the requested length exceeds 2^32 - 1, so anyone
passing in a custom value (defaults to zero for same behaviour as
before) will need an exception check at the call site.
