FPv2: don't add debug candidates to versions globally (#28562)

* debugging

* this test works, but find a better place

* make test more generic to start testing more than timings

no need to run again in another test function. eventually we
can simulate ECUs and have IsoTpParallelQuery work properly

* Revert "make test more generic to start testing more than timings"

This reverts commit 58e8536b1d.

* 2nd try

* clean up

* not even MappingProxyType works

* works

* test that too

* clean up

* refactor to avoid modification online

* revert tests

* more revert

* no longer needed

* clean up
