spirv: Fix stride calculation when lowering Workgroup to offsets
Use alignment to calculate the stride associated with the pointer
types. That stride is used when the pointers are casted to arrays.
Note that size alone is not sufficient, e.g. struct { vec2 a; vec1 b;
} will have element an element size of 12 bytes, but the stride needs
to be 16 bytes to respect the 8 byte alignment.
Fixes: 050eb6389a8 "spirv: Ignore ArrayStride in OpPtrAccessChain for Workgroup"
