D3D11: Remove device lock from Buffer::APIDestroy Refactors pending buffer map tracking to use an intrusive linked list structure with nodes embedded directly in the Buffer class. This ensures efficient O(1) cancellation and avoids heap allocations. Key changes: - Embeds BufferMapRequest nodes in Buffer to track pending maps. - Queue uses an ordered map of intrusive lists for serial processing. - Makes DestroyImpl() thread-safe via CancelScheduledBufferMapping(). - D3D11 overrides UseDeviceGuardForDestroy() to return nullopt.

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
