package/Config.in: make QT libraries entries visible with Qt6

For now the "QT libraries and helper libraries" section was only made
visible when BR2_PACKAGE_QT5 was enabled. In preparation for enabling
some of those libraries with Qt6, we now show this section when
BR2_PACKAGE_QT5 || BR2_PACKAGE_QT6.

All of the 8 packages in this section already had a (redundant)
"depends on BR2_PACKAGE_QT5" in their own Config.in file, so the only
functional change of this commit is that the comment "QT libraries and
helper libraries" now becomes visible with Qt6, but it is not followed
by any selectable option. This will be changed in a following commit
enabling one of those libraries with Qt6.
