This change moves the bulk of the existing GPUInfo functionality into an autogenerated source built from a JSON file that describes the GPU vendor and device IDs, with device IDs broken down by GPU architecture. Also adds the fields needed to implement GPUAdapterInfo in Blink to the AdapterProperties. Bug: dawn:1427 Change-Id: I6a8b1fa7a63ec8d71556fc5bb3ae12cfe5abf28b Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/90962 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Brandon Jones <bajones@chromium.org>
