The intended target is OpenCL 1.2, so disable warnings for APIs deprecated after that. This primarily applies to clCreateCommandQueue(), we can't use the replacement clCreateCommandQueueWithProperties() because it was introduced in OpenCL 2.0. Also remove some unnecessary includes from overlay and program filters so that the define is available at the right moment.
