[tint][msl] ArgBufs: detect host-shareable structs inside argbufs

Fixes missing padding in MSL structs for buffer bindings, which was
caused by those bindings being missed by FindHostShareableStructs()
because they're hidden behind pointers in the argument buffer.

Fixes:
- ComputeMultipleDispatchesTests.IndirectOffset
- ComputeMultipleDispatchesTests.ExceedsMaxWorkgroupsWithOffsetNoop
- ComputeLayoutMemoryBufferTests.StructMember
- ComputeLayoutMemoryBufferTests.NonStructMember
- CopyExternalTextureForBrowserTests_Basic.Copy
- CopyTextureForBrowser_Formats.ColorConversion
- CopyTextureForBrowser_ColorSpace.colorSpaceConversion
- ExternalTextureTests.SampleExternalTexture
- ExternalTextureTests.TextureDimensionsWithTextureView
- ExternalTextureTests.SampleExternalTextureDifferingGroup
- ExternalTextureTests.SampleMultiplanarExternalTexture
- ExternalTextureTests.SampleMultiplanarExternalTextureNorm16
- ExternalTextureTests.RotateAndOrFlipSampleSinglePlane
- ExternalTextureTests.RotateAndOrFlipTextureLoadSinglePlaneNotSquare
- ExternalTextureTests.RotateAndOrFlipSampleMultiplanar
- ExternalTextureTests.CropSinglePlane
- ExternalTextureTests.ApparentSizeEffect
- ExternalTextureTests.CropMultiplanar
- ExternalTextureTests.SampleExternalTextureAlpha
- MultipleWriteThenMultipleReadTests.OneBuffer
- ShaderTests.PassMatrixByValue
- ShaderTests.PassMatrixInStructByValue
- TextureComponentSwizzleTest.UseDefaultSwizzleAfterNonDefaultSwizzle
- TextureShaderBuiltinTests.BaseMipLevelTextureView

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.
