[CI] Don't test stuff which does not work due to static python (#38303)

opencv even has 
`message(WARNING "The python module is currently unsupported on Windows
when building static OpenCV libraries")`

In general static python builds don't support extensions on windows as
such a pyd build against a static python can never be used.
What would work -> static extensions linked into a final executable.

There is no proper way to deactivate extensions if python was statically
build on windows.

Two questions remain here:
Should python be build dynamically on windows for static triplets so
that we get a broader CI test? (maybe add a forbidden feature for only
windows&static which allows building the static python instead)
