Nicolas Capens dd988bca84 GN: add a default build target
This target is built when no specific target is specified on the command
line. It avoids building all available targets. Specifically, the
optional use of LLVM as a JIT-compiler by SwiftShader was dominating
compile times.

See the GN reference for details:
https://gn.googlesource.com/gn/+/master/docs/reference.md#the-all-and-default-rules

For now, it's equivalent to the "all" target. Note the latter is an
explicit target, not the implicit one mentioned in the reference.

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
