What does it mean these tests are not part of dynamic subtests?

AFAIK, all basic-* tests are positive test cases & there are 
corresponding negative test cases (invalid-*)

If any positive test executed, the corresponding negative test is 
supposed to skip & vice versa.

Example:
https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html?testfilter=kms_setmode&hosts=shard-glk 


- basic-close-single-crtc: SKIP
- invalid-clone-single-crtc: PASS

- clone-executive-crtc: PASS
- invalid-clone-executive-crtc: SKIP

We are supposed to execute the test, not a cleanup. This will always 
throw the test result as PASS (which is bogus) without even testing 
anything.
