QByteArrayList: optimize 32-bit builds of legacy join() helper

Browse Source 
On 32-bit machines, qsizetype is int, so we don't actually need to
QT_REMOVE_SINCE the QByteArrayList_join() helper, because it didn't
change.

Thanks to Thiago for showing me the QT_POINTER_SIZE trick in a similar
change to QVersionNumber.

Pick-to: 6.3
