[SYCL] SYCL SLAMBench Port

[agozillon]

Port the existing SLAMBench implementation over to see how feasible it is to run a large application with the compiler at the moment: https://github.com/agozillon/syclslambench

This should mostly be working out how to integrate the compiler appropriately with the existing CMake and syclcc script infrastructure. However, integrating it could unearth some problems with the existing compiler infrastructure or existing runtime bugs.

This should start with Integrating the Intel Compilation flow into SYCL SLAMBench and then adding the Xilinx xocc compilation flow to it. Doing it this way should hopefully make life a little easier.
