Add expected results for all of the new E2E tests. The arrayLength()

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.

This reverts commit e5dbe24e94.
Reason for revert: Makes the Tint-Dawn roll fails because of
MSL compilation errors on as_type<uint>(-2147483648):
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
(since without the - it is larger than the max int32).
