ECR #333753 - clc2: disallow implicit function declarations (bug 10328)
In addition, the change fixes the following side-effects:
1. Fix a typo in runtime/.../gpuschedcl.cpp, which fails due to the stricter check in Clang.
2. Unconditionally add sub_group builtins for pipes, without checking if the extension is enabled. See bug 10366.
3. Also added a test in ocl_features_clang to check for the sub_group builtins.
Passes smoke, smoke_clang, precheckin.
Additionally passes new tests added in ocl_features.

ECR #304775 - Add batching to the device enqueue for possible asynchronous execution
- Increase the max device queue size to 512KB. That will allow to pass conformance tests that enqueue more jobs than the queue size.

ECR #304775 - Device enqueuing
- Provide scratch buffer offset for generic address space
- Use single scratch buffer for all available queues. Each queue will have a unique subbuffer in the global buffer

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

ECR #304775 - Device enqueuing
- Switch to the single thread scheduler for now(the current version isn't friendly for single thread). Hopefully it's a temporary solution until synchronization issue with multithreaded scheduler will be identified.
