QArrayDataOps: fix QList range ctors with mixed value_type in C++20 builds

The QList<X> range ctor is supposed to accept iterators with
value_types convertible to X, e.g. tst_qitemselectionrange passes
iterator to a container of QModelIndex to the ctor of a
QList<QPersistentModelIndex>. But copyAppend() is not a template, so
trying to pass QModelIndex* when QPersistentModelIndex* is expected
errors out.

Fix by taking the copyAppend() path only if the types match.
