DawnTest: Gather adapters on environment creation for filtering backends This moves the creation of the Instance and Adapter discover to environment creation. It allows programatically filtering test parameterizations based on what is available on the system instead of relying on what is enabled at compile time. Because of an issue with the Vulkan validation layers, the instance and adapters are created twice. Once in environment creation, and once on environment set up. The Vulkan validation layers use static global mutexes which are unsafe when Chromium's test launcher forks the launcher process between environment creation and SetUp.

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:
