According to the discussion[1], the sum of all the user-defined
inter-stage component count and all the inter-stage builtin component
count should be no more than MaxInterStageShaderComponents (currently
in Dawn it is always 60).

SPIR-V spec states:
> Each structure-type member that is a matrix or array-of-matrices must have be decorated with a MatrixStride Decoration
As already pointed out in https://dawn-review.googlesource.com/c/tint/+/59840, we were not handling arrays-of-matrices.
To do this correctly, we need the ast::StrideDecoration to be placed on the Matrix type, which is a much bigger change to support.
For now, chase the type, and error if we have a custom MatrixStride on an array of matrices, otherwise drop the decoration.

Fix for crbug.com/dawn/1049, where setting a pipeline without drawing can
prevent bind groups from being applied later. This occurs because the mask
for the pipeline is being saved but not its layout, because the bind
groups are never applied. This changes to only save the mask if the bind
groups are applied (the pipeline is used in a draw or dispatch).

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.
