[dawn][native] Fixes TSAN issues when running without implicit sync.

- When running without implicit synchronization, there isn't a lock
  protecting access to the Defer object in Device. This resulted in
  TSAN complaining about potential data races. Instead, if we are
  not running with implicit synchronization, and hence don't have a
  device lock, we don't need to create defer object.
- Note that this only fixes one of the issues observed in the TSAN
  runs, and does not completely fix all the issues yet.

Dawn, a WebGPU implementation

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:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
