We cannot remove the overload using QT_REMOVED_SINCE, because a qint64
lvalue in the new overload will not bind to an uint& parameter, so the
old code would not compile.
Deprecate the old overload, and add a unit-test that makes sure that
it still behaves correctly.
This commit also introduces the new deprecation macros that are
required to do the deprecation in Qt 6.11.
