Module detection flow update to tag copper passive cables as software…

… control (sonic-net#19476)

- Why I did it
On Mellanox platforms, currently only CMIS active ports can be controlled by the SW, and all copper modules are controlled by FW.
We want to let Sonic control passive copper modules as well, for CMIS and SFF (sff8636 and sff8436).

- How I did it
I updated the module detection flow to tag CMIS and SFF passive modules as SW control.

- How to verify it
Manual tests.
