Returns the SYCL application interoperability native backend object associated with the context associated with the SYCL queue that the host task was submitted to.
The native backend object returned must be in a state where it is capable of being used in a way appropriate for the associated SYCL backend.

Receives a SYCL accessor that has been defined as a requirement for the command group, and returns the underlying OpenCL memory object that is used by the SYCL runtime.
If the accessor passed as parameter is not part of the command group requirements (e.g. it is an unregistered placeholder accessor), the exception sycl::invalid_object is thrown asynchronously.

Returns an underlying native backend object associated with teh queue that the host task was submitted to.
If the command group was submitted with a secondary queue and the fall-back was triggered, the queue that is associated with the interop_handle must be the fall-back queue. The native backend object returned must be in a state where it is capable of being used in a way appropriate for the associated SYCL backend. It is implementation-defined in cases where the SYCL queue maps to multiple underlying backend objects. It is responsibility of the SYCL runtime to ensure the backend queue returned is in a state that can be used to dispatch work, and that other potential backend command queues associated with the same SYCL command queue are not executing commands while the host task is executing.
