Fixes #5597
Since list views can be stored out of order and because there can be nulls at the end of the vector, we have to calculate the length of the child vector by looking at all views in the vector.
Note that this does not take validity into account, as I have no idea if DuckDB allows for complete garbage in their list views if they are null. At least in Arrow, that is not allowed.
Also adds 3 regression tests.
