[dawn][vk] Use VkDriverId to decide workaround toggles.

The IsAndroidFoo conditions matched GPUs only on Android when the same
drivers may be used on ChromeOS. To broaden the checks without
penalizing other drivers, PhysicalDeviceVk now uses VkDriverId that lets
us detect which driver we're running on. Assuming all the proprietary
drivers are the same source (and that the workarounds are for driver
issues, not hardware issues), this gives more precise conditions for
when the workaround is needed.

Also group toggles under IsIntelMesa together.

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.
