CMake: Don't build cmake build tests as macOS universal

We want standalone tests added by qt_internal_add_test to be built as
universal executables, so we can build them on an intel machine and
run them on an ARM machine.

But CMake build tests will be built on the final machine that runs the
tests and it might lack a universal SDK. That's why they should be
built only targeting the architecture of the machine they're running
on.

Change the generated qt.tooclhain.cmake file to allow opting in or out
of building projects with the same architectures as Qt was configured
with.

Now standalone tests will be multi-arch, but CMake build tests will be
single-arch.
