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.
