API device_wrap_native is not usable for OpenCL JIT target.

[magpier84]

Halide's Buffer has the method device_wrap_native. In case of OpenCL it supposed to be used for wrapping externally created cl_mem object. But it is not possible to create cl_mem object in case of JIT because cl_context is not available and halide_acquire_cl_context can't be overridden.
So, the questions is: is it possible to retrieve cl_context(and cl_command_queue) or provide it for Halide JIT?

Thanks!
