Is your feature request related to a problem? Please describe.
With pylibcudf largely complete in containing the necessary APIs for cudf Python (xref #15162), the cudf Cython layer (cudf._lib) should be largely unneeded now as pylibcudf provides a public interface to access libcudf.

Describe the solution you'd like
Ideally to fully remove the cudf._lib directory and stop developing Cython binding for this directory.

Each Cython file in cudf._lib should be able to be converted to a Python in cudf.core._internals (or cudf.core._plc?)

Additional context

Open Questions/Considerations

  1. cudf Cython spill locks whenever calling pylibcudf algorithms that operate on columns (e.g. nans_to_nulls), while there's currently no way to replicate spill locking with using pylibcudf alone.

  2. cudf Cython also defines Cython classes that back cudf Python columns and scalars. Ideally cudf Python should just be able to define these objects in Python, but it's not clear yet (to me) if there's some aspect that needs to be defined in Cython.
