Add ComputeManager; add SmoHooks for getting ClDevices, buffers

We added a new centralized OpenCL Compute manager. This can later
be extended to support CUDA, SyCL, etc. SMO can be configured at
build time to choose which API it will use for compute.

Moreover, the ComputeMgr allows us to register buffers which are
available to all cl_contexts.
