Description

cudf currently has many APIs that take in std::vector as one of its input parameters. For example: https://github.com/rapidsai/cudf/blob/c01a2a41b7d57a1360324270101d9304fbc9515f/cpp/include/cudf/table/table_view.hpp#L235

We should replace the std::vector parameter by host_span wherever possible.

Contributor guide

Research direction
Identify all API endpoints in cuDF that accept std::vector as a parameter and replace them with host span, ensuring backward compatibility and proper memory management.
