[fuzz] Improve normalization and cleanup experiment mode

When calculating normalization, attempt to account for the time spent
ingesting the corpus on the initial run, so that the normalization
factor is reflective of the long run steady state instead of being
biased towards initialization.

Additional cleanups in the experiment mode implementation, including;
unifying how fuzzers are called, how run counts are parsed out of the
logs, and making sure that failed runs don't accidentally get marked as
finished when restarting due to how the profiling data looks.

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.
