This change refactors dawn-defined buffer and texture usages. It groups buffer usages together, and groups texture usages together, in order to avoid values conflict. It also removes kReadOnlyStorageTexture because its definition has already been removed. Bug: dawn:485 Change-Id: I8c772ebadd3d276905fbcdb3283f0d5d89f74dd6 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/65680 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Yunchao He <yunchao.he@intel.com>
