[tint][val] Improve type validation for IO attributes

Adds in missing type testing for IO attributes, so that non-allowed
types are rejected, instead of silently getting through

Clean up of the BuiltinChecker for how it reports type errors

Added type error checking to IOAttributeChecker

Merges kAllowWorkspacePointerInputToEntryPoint,
kAllowPrivateVarsInFunctions, kAllowPointersAndHandlesInStructures into
a single capability kMslAllowEntryPointInterface

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.
