[razdoburdin]

Hi, I continue adding of sycl support (https://github.com/dmlc/xgboost/pull/9691, https://github.com/dmlc/xgboost/pull/9846, https://github.com/dmlc/xgboost/pull/9800, https://github.com/dmlc/xgboost/pull/10011, https://github.com/dmlc/xgboost/pull/10045). By this PR I add the next part of the training-related code for the sycl devices. Here I add logic related to RowSetCollectionan and the related tests. This PR itself doesn't add any new functional, but I plan to combine all related parts one by one to a launchable sycl-training.
