clover: implement CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE

Work-group size should always be aligned to subgroup size; this is a
basic requirement, otherwise some work-items will be no-operation.

It might make sense to refine the value according to a kernel's
resource usage, but that's a possible optimization for the future.
