This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.
The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.
The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

Reason for revert: This is making the Dawn -> Chromium roller fail.
https://github.com/KhronosGroup/SPIRV-Tools/pull/4407 introduces a new mandatory parameter to the spvtools::fuzz::Fuzzer constructor, which does not exist in Chromium's version of SPIRV-Tools (d9f89257855a2784323512cd9568b6610bcae581).
The roll of SPIRV-Tools into Chromium is currently blocked by another issue, and is a couple of weeks behind ToT. See https://autoroll.skia.org/r/vulkan-deps-chromium-autoroll.
Note, that https://github.com/KhronosGroup/SPIRV-Tools/pull/4407 is going to block the eventual roll of SPIRV-Tools in Chromium, as there's no way this code can compile for both pre and post roll.
I'll try and fix this after unblocking this roll

Reason for revert: Makes the Tint-Dawn roll fails because of

as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed
as_type<uint>(-2147483647) compiles fine, so this is most
likely because the MSL compiler types the literal as a long

When building a vector via tint::writer::AppendVector, and the
vector argument is already a vector constructor, expand that
vector constructor into its components only when those components
are all scalars. This avoids a type breakage which can occur with cases
like this:
vector argument is:
vec2<i32>(vec2<u32>(0u,1u))
scalar argument is:
2
Before this fix, the result was:
vec2<i32>(0u, 1u, 2);
But should be this instead:
vec3<i32>(vec2<u32>(0u,1u),2)
This was noticed in SPIR-V writer output when forming a coordinate
vector from a an unsigned WGSL coordinate vector with a signed array
vector.
