SYCL Kernel Implementations

[homerdin]

Opening issue to track SYCL kernel implementations in the rajaperf_sycl branch. Also includes support for auto work_group_size selection if 0 is given as a buildable block_size. Yes below indicates that the kernel has been implemented in a fork. Combining the implementations into the rajaperf_sycl branch is in process.
