FPGA: Add in template argument list after template keyword (#2405)

This PR adds a template argument list after the template keyword. This is now required with newer versions of SYCL.

This change also adds a print message for the DEVICE_FLAG variable so that we are not getting any CMake unused variable warnings when running this design.
