Generate instances of types in the CMake tests.

All modules currently have a test_modules CMake test. The
new module_includes test has very similar requirements, and can
obsolete the hand-maintained test_modules tests in all modules.

After all test_modules have been removed in other repos, the
module_includes test can be renamed to that name.

The types chosen need to have a constructor which can be invoked
with no arguments. QtConcurrent has no public classes which fit
that description so it is still tested separately
