Work with newer thrust and libcudacxx (#8432)

* Thrust 1.17 removes the experimental/pinned_allocator.

When xgboost is brought into a large project it can
be compiled against Thrust 1.17+ which don't offer
this experimental allocator.

To ensure that going forward xgboost works in all environments we provide a xgboost namespaced version of
the pinned_allocator that previously was in Thrust.

* Update gputreeshap to work with libcudacxx 1.9
