clc: rework optional subgroup feature

Browse Source 
OpenCL 3.0 core requires __opencl_c_subgroups to be set, the OpenCL
cl_khr_subgroups extenions can only be enabled if and only if the driver
guarentees independent forward progress between subgroups.

See CL_DEVICE_SUB_GROUP_INDEPENDENT_FORWARD_PROGRESS for more information.
