Use CL_KERNEL_WORK_GROUP_SIZE more often (#2435)

Browse Source 
Drivers _may_ choose to advertise values for
`CL_DEVICE_MAX_WORK_GROUP_SIZE` or `CL_DEVICE_MAX_WORK_ITEM_SIZES` that
kernels without a `reqd_work_group_size` are not able to be launched
with.

The CTS should therefore make sure that the local_size passed to
`clEnqueueNDRangeKernel` does not exceed `CL_KERNEL_WORK_GROUP_SIZE`

This fixes it up in two places I've noticed this not happening.
