    Qt6: Update to 6.10.1

    I'm not giving the usual fanfare. This has been an absolute slog.

    Ports changes:
    qt6-base: Added WAYLAND option. This is congruent with the X11 option.
              We really don't recommend disabling this option, but it is
              available for advanced users who don't want wayland for
              whatever reason.


appears to cause qbittorrent to crash, see bug#291988.

The Q_UNREACHABLE macro is executed in this function:
840│ Q_NEVER_INLINE
841│ void QBasicMutex::unlockInternal(void *copy) noexcept
842│ {
843│     Q_ASSERT(copy); //we must be locked
844│     Q_ASSERT(copy != dummyLocked()); // testAndSetRelease(dummyLocked(),
0) failed
845│
846│ #  if defined(Q_OS_FREEBSD) || defined(Q_OS_LINUX) || defined(Q_OS_WIN)
847│     // these platforms always have futex and have never called this
function
848│     // from inline code
849├───> Q_UNREACHABLE();
850│ #  endif

Building qbittorrent with WITH_DEBUG=yes is a workaround for unclear reasons.
