Use Chromium's abseil build files when building in ANGLE

Dawn's abseil build files at third_party/gn/abseil-cpp have to stay
because Skia is unable to build with the Chromium GN files.

ANGLE frequently updates abseil to match Chromium's and this often
breaks builds when Dawn's build files cannot work with the new abseil
checkout.

Add a new build_with_angle variable to know when building in an ANGLE
checkout and use the chromium abseil build files in that situation.

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.
