sycl : add PAD_REFLECT_D1 operator support (ggml-org#16145)

* sycl: add PAD_REFLECT_D1 operator support

* docs(ops): regenerate docs/ops.md

* remove trailing whitespaces

* style: fix editorconfig issues — trim trailing spaces and normalize EOLs

* fix: move PAD_REFLECT_1D case outside of fall-through block
