Small refactor for hist builder. (#8698) 
- Use span instead of vector as parameter. No perf change as the builder work on pointer.
- Use const pointer for reg tree.

Work with newer thrust and libcudacxx (#8454) 
* 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.

Split up column matrix initialization. (#8060) 
* Split up column matrix initialization.

This PR splits the column matrix initialization into 2 steps, the first one initializes
the storage while the second one does the transpose. By doing so, we can reuse the code
for Quantile DMatrix.
