Don't export Qt6::ATSPI2_nolink target in Qt6GuiTargets.cmake

We don't have any APSPI2 includes in our public headers and should
therefore not export the target that provides ATSPI2 include paths for
consumers.

Link against PkgConfig::ATSPI2 instead of the _nolink target.
The former will not be exported.

Pick-to: 6.2
Fixes: QTBUG-97023
