SYCL building blocks for C++ libraries

" summary

SYCL (SYCL 1.2 on top of OpenCL 1.2) is presented as a single-source C++14 model with concrete APIs: queues, command groups, buffers and accessors, plus parallel_for and hierarchical parallelism for kernels. Examples show templated device functions, a buffered device stream for formatted output, a host fallback queue, and building libraries: VisionCpp DSL, a SYCL TensorFlow backend (partial mainline merge), and ComputeCpp Community Edition running on Intel CPUs and AMD GPUs. Performance portability and embedded SPIR are demonstrated as working implementations.
