[FEA] Use the conda package for croaring instead of fetching via CPM in libcudf tests and benchmarks #20002
Description
Description
Follow up from #19237
Right now, we use CPM to fetch and build roaring package needed in libcudf tests and benchmarks. Instead, we may use the croaring package from conda-forge for conda builds. However, for finding the conda package to work properly we will need RoaringBitmap/CRoaring#739 (as well as propagation to the conda package).
Steps to reproduce
See CI from here
