Link Speed Detection and Report

Added support to detect and report 1600G link speed when using ConnectX-9 SuperNIC, ensuring link-speed negotiation and status reporting correctly reflect 1.6T-capable connections in tools and telemetry.

Windows INF Service Registry Key Modernization

These changes are transparent to users and do not affect the user experience.
