This patch enables one texture to be used as both write-only storage texture and sampled texture in one compute pass. Note that while we don't need to check the usage scope of a texture in the whole compute pass scope, we still need to verify one texture cannot be bound to multiple bindings that are used in one dispatch at the same time. This check will be added in the following patches. This patch also adds tests to ensure a texture can be used as the following binding types in one compute pass: - read-only storage + sampled - write-only storage + sampled - read-only storage + write-only storage BUG=dawn:267 TEST=dawn_unittests Change-Id: Ibff2b005a5269a0bfa254e0417de4920758add39 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/20120 Commit-Queue: Jiawei Shao <jiawei.shao@intel.com> Reviewed-by: Austin Eng <enga@chromium.org>
