Use imageSize() on images, not textureSize().
In GLSL, the LOD parameter to textureSize() is mandatory for
sampled textures, so emit a default 0 if not supplied. (Also, don't pack
the level into the coords argument; that's an HLSLism.)
GLSL returns the array size of array textures in the final component
of textureSize(); remove it for WGSL.
Write the subtype of storage images correctly (uimage*, iimage*, etc).
This required a bit of cleanup to move "writeonly" ahead of subtype
emission.

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.

Brings the number of failing tint end to end tests for MSL down to 19/1098.
The WG still haven't found consensus on reworking these two intrinsics.
It's very likely that their signature will change so that they return a structure instead of returning a value and outputing another as a pointer.
Until the WG makes a decision, let's implement these according to the current spec.
Some overloads are still failing due to MSL missing overloads of the pointer parameter being in the `threadgroup` address space.
I'm holding off fixing these until we know what's happening with these intrinsics.
