Add missing optional core language features to CL3.0 PCH options

Please refer to
https://www.khronos.org/registry/OpenCL/specs/3.0-unified/html/OpenCL_C.html#features

E.g. adding __opencl_c_device_enqueue/__opencl_c_atomic_scope_all_devices
can fix OpenCL CTS test_device_execution and test_c11_atomics.
