* Remove invalid assumption from sub-group tests
The sub-group dispatch tests were making the invalid assumption that
querying the local size (via `CL_KERNEL_LOCAL_SIZE_FOR_SUB_GROUP_COUNT`)
for a sub-group count obtained from a
`CL_KERNEL_SUB_GROUP_COUNT_FOR_ND_RANGE` with local size `{x, y, z}`
will result in the same local size i.e. that
`CL_KERNEL_LOCAL_SIZE_FOR_SUB_GROUP_COUNT` is the inverse of
`CL_KERNEL_SUB_GROUP_COUNT_FOR_ND_RANGE`. To take a trivial example
consider the case that there is only ever one sub-group per work
group(i.e. sub-group == work-group). Then regardless of the local size
passed to `CL_KERNEL_SUB_GROUP_COUNT_FOR_ND_RANGE` the sub-group count
will always be `1`, and `CL_KERNEL_LOCAL_SIZE_FOR_SUB_GROUP_COUNT` can
return any valid local size since all local sizes result in `1`
sub-group.
