This reverts commit b6a80b321e8fa0b79d9a947656ea0ad649ed5a3c. Reason for revert: dawn_end2end_tests are failing on the Chromium GPU FYI bots. Example here: https://ci.chromium.org/p/chromium/builders/ci/Win10%20FYI%20Release%20%28NVIDIA%29/4226 Original change's description: > Destroy backend implementation for Buffers > > Destroy can be used to free the GPU memory associated with resources > without waiting for javascript garbage collection to occur. > The buffer is validated at submission to the queue. > So any buffer that has been destroyed before submission, will then > invalidate the submit and result in an error. > > Bug: dawn:46 > Change-Id: I40df56ce97baef01deea7552d7a6d40b558fc985 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/5320 > Reviewed-by: Kai Ninomiya <kainino@chromium.org> > Commit-Queue: Natasha Lee <natlee@microsoft.com> TBR=cwallez@chromium.org,kainino@chromium.org,enga@chromium.org,rafael.cintron@microsoft.com,natlee@microsoft.com # Not skipping CQ checks because original CL landed > 1 day ago.
