CMake: Fix single standalone tests to use same Qt C++ language std

When using qt-cmake-standalone-test, we didn't tell CMake to use the
same C++ language standard that Qt used when it was configured.

We did tell CMake to do that when configuring tests with
qt-internal-configure-tests via the qt_build_tests macro.

To ensure the proper standard is set, we also need to
find_package(Qt6Core), because the std flag is derived from the
QT_FEATURE_cxxyz flag which is set by Core.
