[tint] Add sem::Load for swizzle from a pointer

Without the implicit load, conversion to IR fails (found by fuzzer in
the linked bug). This also causes the alias analysis and uniformity
analysis to miss certain errors.

Unlike all other cases where the load rule is invoked, the type of the
source expression here is a pointer, since there is also an implicit
dereference. This change allows `sem::Load` to have a pointer
expression as its source type to support this.

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.
