[tint] Support texture-format-tier1

Tint changes:
- Update core/texel_formats.def
- Update language specific def files:
  - Classify new texel formats as yielding f32, i32, u32 data
- Update language-specific printers
- WGSL resolver validation
- Update IR proto
- Update IR validation test for message change
- Update error message in unit test
- Update resource binding enums, and inspector mappings
- Generate skips for GLSL backend end2end tests

Dawn changes:
- Update resource binding mappings from Tint inspector

Update expectations for validation tests that should pass but
need to be updated in CTS.

This needs additional changes in dawn/native/Format.cpp, which is
already in flight

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.
