Add NT-version-scoped exclusions and a parallel multi-version CI matrix

Exclusions:
- Add MinNtTargetVersion/MaxNtTargetVersion columns to exclusions.csv so a row can apply
  only within an _NT_TARGET_VERSION build-number range (parsed from -NtTargetVersion, e.g.
  22000 from 10.0.22000). Import-SampleExclusions filters this range at load time alongside
  the existing build-number range; blank = unbounded.
- Exclude the samples that fail only when linking against older library sets, with the
  reason taken from the build logs: audio.sysvad (<=22000, KSJACK_DESCRIPTION3);
  network.netadaptercx.netvadapter and network.wlan.wificx (<=22621, NDIS/DDI version);
  powerlimit.plclient/plpolicy (<=22621, POWER_LIMIT_ATTRIBUTES); storage classpnp/storahci
  (<=22621, STOR_ADDRESS_TYPE_NVME, Debug-only) and storage.msdsm (Debug|x64). usb.usbview is
  intentionally NOT excluded: it fails on every version for a known host reason (missing
  .NET 4.7.2/4.8.1 targeting packs).

CI:
- ci.yml and ci-pr.yml: add _NT_TARGET_VERSION as a manual matrix axis (4 newest versions,
  latest-first) so each version x configuration x platform runs on its own parallel runner.
- Build-Samples.ps1 and Join-CsvReports.ps1 now write an easy-to-scan Markdown summary to
  GITHUB_STEP_SUMMARY: each build job shows counts and a failures table with the first error;
  the report job shows per-version totals and a consolidated failures list, plus the
  colour-coded sample x version HTML/CSV overview.
