This change is a preparation for making the compute pass track the synchronization scope usages per dispatch instead of for the whole pass. This CL just separates the Compute and RenderPassResourceUsage types. This requires making the difference between SyncScope/ComputePass/RenderPass ResourceUsageTracker instead of having a single combined tracker. This change also duplicates SetBindGroup by removing the common handling in ProgrammablePassEncoder and putting it in ComputePassEncoder and RenderEncoderBase. This is necessary because the UsageTracker types are now split, but it will also help have different handling of SetBindGroup for compute and render in follow-up CLs. There are no functional changes.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress 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:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
