  "message": "WebGPU Backend: Implement SharedTextureMemory, SharedFence (Metal)\n\nAdds starting implementation of SharedTextureMemory, SharedFence\nin the webgpu backend (when inner backend is Metal). This CL should\nsetup framework and indicates future implementation route for other\ninner backends.\n\nNotes:\n- Pending Shared Access:\nOnly call wgpu.sharedTextureMemoryAccess in Texture::SynchronizeTextureBeforeUse if there is GPU Access.\n- Added webgpu::Texture::SynchronizeTextureBeforeUse and PrepareResourcesForSyncScope in webgpu::CommandBuffer to correctly track and sync texture states in frontend.\n- In metal a GetCommandsScheduledFuture is needed to get a future to wait when EndAccess is called. Since the public WGPUQueue API does not currently expose a way to retrieve a \"commands scheduled\" future, we do instanceWait on future returned by the inner queue onSubmittedWorkDone to block till the end of access. This is a CPU only wait.\n\nBug: 483147423\nChange-Id: I0d248d61c770e6a9fdbaec7ec72e9243d7bd363b\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/292155\nReviewed-by: Loko Kung \u003clokokung@google.com\u003e\nCommit-Queue: Shrek Shao \u003cshrekshao@google.com\u003e\n",
