PipelineBase now collects the EntryPointMetadata for all its stages which makes the rest of the code agnostic to the entrypoint name (except D3D12 and OpenGL that required transition hacks and will be fixed in follow-up CLs). Bug: dawn:216 Change-Id: I643da198cb2a20a9d94d805a2dc783d6d4346ae9 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/27260 Reviewed-by: Ryan Harrison <rharrison@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org>
