[PATCH i-g-t 2/2] tests/kms_feature_discovery: Log output count on skip

[Swati Sharma <swati2.sharma@intel.com>]

Add a num_outputs counter to feature discovery subtests
that iterate connected outputs (dp-mst, hdr, vrr, dsc).
Print the count in the igt_require_f message so it's clear
how many outputs were checked when a feature is not found.
