FindLibXslt: Mark LIBXSLT_LIBRARY and LIBXSLT_EXSLT_INCLUDE_DIR as advanced
Make them consistent with other artifacts' cache entries. Also drop mark on non-cache variable.
Original Description
These two variables show in the cmake-gui without advanced option checked. Perhaps they need to be marked as advanced.Topic-rename: FindLibXslt-cache-advanced
