R2.14

• Added support for Intel GPUs via SYCL.
  • SYCL at present does not support runtime compilation required for bm3dcuda_rtc's counterpart.
  • Pre-compiled binary for pre-gen12lp devices will be dropped starting from the next release.
  • TODO: runtime sub-group size selection. (Xe2 is 16 wide)
