Subject: [SYCL] This PR adds the minimum modifications to the Eigen
 unsupported module required to run it on devices supporting SYCL. *
 Abstracting the pointer type so that both SYCL memory and pointer can be
 captured. * Converting SYCL virtual pointer to SYCL device memory in Eigen
 evaluator class. * Binding SYCL placeholder accessor to command group handler
 by using bind method in Eigen evaluator node. * Adding SYCL macro for
 controlling loop unrolling. * Modifying the TensorDeviceSycl.h and SYCL
 executor method to adopt the above changes.
