[dawn] Remove default value for --enable-backend-validation

--enable-backend-validation defaulted to 'partial' which is unintuitive,
and also the opposite of Chromium's --enable-dawn-backend-validation:
https://source.chromium.org/chromium/chromium/src/+/main:gpu/command_buffer/service/service_utils.cc;l=285;drc=e53e5009a806f9dbc2fb7fca2543326f3c644611

Remove the default so it always has to be specified.

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.
