reader/spirv: Handle the MatrixStride decoration Add `transform::DecomposeStridedMatrix`, which replaces matrix members of storage or uniform buffer structures, that have a [[stride]] decoration, into an array of N column vectors. This is required to correctly handle `mat2x2` matrices in UBOs, as std140 rules will expect a default stride of 16 bytes, when in WGSL the default structure layout expects a stride of 8 bytes.

msl: Handle buffer variables in transform This removes a lot of awkward logic from the MSL writer, and means that we now handle all module-scope variables with the same transform.
