Subject: Modifying TensorDeviceSycl.h to always create buffer of type uint8_t
 and convert them to the actual type at the execution on the device; adding
 the queue interface class to separate the lifespan of sycl queue and
 buffers,created for that queue, from Eigen::SyclDevice; modifying sycl tests
 to support the evaluation of the results for both row major and column major
 data layout on all different devices that are supported by Sycl{CPU; GPU; and
 Host}.
