We already have hard-coded logic to disable adding these tests to the `check-all` target in various cases. It's handy to have a CMake option to disable if in an environment where the tests don't work and you want `check-all` to work as expected.

By my understanding there's no ability to treat CMake options as tri-state, where I'd be able to tell if it was explicitly st to ON, explicitly set to OFF, or left to the default. So the new option is just "force disable" rather than allowing a force enable/

CC also @<!-- -->linux4life798 as another contributor I can see from the commit logs.
