reader/spirv: Partially handle MatrixStride on matrix arrays

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.
