Cable reports now include Thunderbolt controller data

What's new

CIO data in cable reports. When you report a cable that has an active Thunderbolt link, the report now includes a "Thunderbolt link context" section with CableGeneration, CableSpeed, Generation, AsymmetricModeSupported, LegacyAdapter, and LinkTrainingMode from the TB controller. This helps us map the CIO value tables faster without needing separate ioreg follow-ups. USB-only cable reports are unaffected.
Privacy-conscious. The downstream device identity (dock/monitor name, vendor ID, device ID) is deliberately excluded from the report.
