tint: always pass in earliest evaluation stage to intrinsic table lookup

This fixes cases where input args of different type are mixed between
constant and runtime evaluated. We initially did this only for builtins
(https://dawn-review.googlesource.com/c/dawn/+/104545) to fix cases like
`select`, but we also need this for binary operators like shift
left/right that also take args of differing types. For consistency, this
change also includes passing in the earliest evaluation stage when
looking up unary ops and initializer/conversions.

Bug: tint:1713

Dawn, a WebGPU implementation

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:

  • 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.
