The item widgets all have an API flaw: getters and setters for the text
alignment deal with int instead of Qt::Alignment.
Deprecate the existing setters and introduce others taking
Qt::Alignment. Store the alignment directly into the item widget (now
that views know how to handle it).
We can't change the getters without cluttering the API, so make that a
Qt 7 change. Users can prepare by forcibly casting the return value to
Qt::Alignment; this is going to work in Qt 6 and 7.
While at it: streamline the handling of Qt::CheckStateRole as well,
avoiding to rely on a pointless Qt::CheckState to int conversion
through QVariant (the setter stores a Qt::CheckState, but the getter
retrieves an int and converts it to a Qt::CheckState).
