COMPMID-417 Checking CL non uniform support at runtime.
What have been done in the ticket are:
1. Add support to check whether cl-non-unform-workgroup is supported at
runtime
2. Add helper function to check the CL version at runtime
3. Add boolen to check whether CLSecheduler's init has been called.
