The Windows 2019 Enterprise SKU is based on RS5 but is missing support for WGC. This changes adds a function IsWgcSupported which will check that the API is actually present, which should be more robust than just performing a version check. Bug: webrtc:13932 Change-Id: Ib6a2278f316b9b86671df77fd37468c79564d655 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/258163 Reviewed-by: Alexander Cooper <alcooper@chromium.org> Commit-Queue: Austin Orion <auorion@microsoft.com> Cr-Commit-Position: refs/heads/main@{#36506}
