ECR #304775 - Device enqueuing
- Use atomic fetch for enqueue flags
- Switch to a multithreaded scheduler
- Add a workaround for Linux host_multi_queue failures. Linux has only 2 queues, but the test allocates multiple host queues and the same HW ring can be used

EPR #304775 - temporarily disable the SVM fine_grained_buffer support for OpenCL 2.0 on discrete GPUs, because the feature is supposed to release in 14.50. After the 14.40 is branched, we will enable it again on stg.
