CMake: Provide a qt-internal-configure-tests script

This is meant to be called by our CI instructions to build standalone
tests of a Qt repository.

Currently it just calls qt-cmake with
-DQT_BUILD_STANDALONE_TESTS=ON, but it might contain more things in
the future.

The script also simplifies configuring standalone tests locally, due
to not having to remember the name of the magical variable.

Change our CI instructions to use the new script.
