Add an option to run cuIO benchmarks with pinned buffers as input

[vuule]

Description

Adds io_type::PINNED_BUFFER, which allows cuIO benchmarks to use a pinned buffer as an input. The output is still a std::vector in this case, same as with io_type::HOST_BUFFER. Also stops the used of cudf::io::io_type in benchmarks, to allow benchmark-specific IO types, such as this one.

TODO: Run multithreaded parquet benchmark with pinned and pageable input on a lab system.
