Refactor test name truncation

Refactors the logic used for determining if test names need to be
truncated in order to fit within the 256 character limit for ResultDB.

Previously, we checked if the test class + some fixed value + the
sanitized name was less than some arbitrary number of characters. This
was problematic since it did not cleanly take into account any prefixes
added to the test class or test names that were significantly longer
than the fixed value we used, leading to cases where tests were not
truncated when they should be.

Now, we keep track of the longest test name we've seen in the wild and
truncate if that + the sanitized parameters are over a threshold.

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.
