[Mellanox] Add CMIS Host Management Files to 'show techsupport' Dumps (…

…#3501)

- What I did
For Mellanox platforms, I added the following CMIS host management-related files to the 'show techsupport' dumps (if they exist): sai.profile, pmon_daemon_control.json, media_settings.json, optics_si_settings.json, and autoneg.status.

- How I did it
I copied the relevant files from the SKU/platform folder and ran the 'show interface autoneg status' command to store the auto-negotiation status for all ports.

- How to verify it
Run 'show techsupport' and verify that autoneg.status is located in the 'dumps' directory and that the other files are present in the cmis-host-mgmt path within the generated dump.
