Added D3D12Error to check HRESULTS and return error messages with the correct error names. Remove ASSERT_SUCCESS from D3D12 backend and use MaybeError and ResultError instead to handle errors. Bug: dawn:19 Change-Id: Idf2f1987725e7e658bd29a9b13653125ab43c564 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/12000 Reviewed-by: Rafael Cintron <rafael.cintron@microsoft.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org>
