[PATCH i-g-t 0/2] tests/intel/kms_tbt: Add DP tunneling validation tests

[Kunal Joshi <kunal1.joshi@intel.com>]

Add an IGT test binary (kms_tbt) that validates the DP tunneling
debugfs ABI exposed by drm/display/dp_tunnel and consumed by
i915 / xe. Pairs with the kernel DP-tunnel debugfs RFC series.

Patch 1 adds a connector-enumeration helper backed by
libdisplay-info for look-up by EDID serial / MST PATH across
re-probes, plus clock-based mode-selection utilities.

Patch 2 is the kms_tbt test: 18 single-display subtests and 9
multi-display / MST subtests covering BWA toggle, bw_limit cap
injection, suspend/resume, and mode filtering.
