[FEA] Make use of cached_property in Cython classes once we update beyond 3.0.11

[vyasr]

Is your feature request related to a problem? Please describe.
Currently various cdef classes in cudf and pylibcudf do not leverage caching as much as they could. This is because, until recently, Cython did not support the cached_property decorator on cdef classes. This feature was implemented in cython/cython#6179 and should be available in the next Cython release, either 3.0.12 or 3.1.0.

Describe the solution you'd like
Once cudf updates to requiring a sufficiently new version of Cython to build, we should start using cached_property. One of the first places this could be used is in the OrcColumnStatistics class in pylibcudf (see https://github.com/rapidsai/cudf/pull/16042/files/4328460b9f9eeaf88417d616f76a006c6e6e5ca8#r1741811824).

Describe alternatives you've considered
We could manually cache the values quite easily, but since the Cython feature is nearly available we may as well wait and save ourselves the effort.
