D3D11: Trigger Flush in ReduceMemoryUsageImpl() to force res cleanup.

When we destroy a D3D11 resource, the D3D11 runtime actually defers
the real destruction. In order to force deleting the resource for good,
we need to call Flush.

This CL implements the ReduceMemoryUsageImpl() in DeviceD3D11 so that
when being idle:
- All pending resource deletions will be flushed.
- All driver's allocated resources will be trimmed.

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.
