Native bindings to the intel_mem_force_host_memory extension.

This extension allows an application to override driver heuristics to force allocation of a buffer memory object in host memory. Host memory is described in the cl_intel_unified_shared_memory extension.

Allocating a buffer memory object in host memory trades off wide accessibility and transfer benefits for higher per-access costs. Buffer memory objects in host memory may also be subject to additional usage restrictions.

Requires OpenCL 1.2.
