* Removed hardcoded -cl-std=CL2.0 build option from progvar tests
Fixes issue #1380https://github.com/KhronosGroup/OpenCL-CTS/issues/1380
These changes will query the device for the latest supported CL C
version instead of using a hardcoded value. The create_single_kernel_helper
function queries for the latest CL C version internally, so calls to
create_single_kernel_helper_with_build_options were replaced with calls
to create_single_kernel_helper instead.
* Fixed formatting
