Pass obj info by reference instead of by value. (#8889)
- Pass obj info into tree updater as const pointer.

This way we don't have to initialize the learner model param before configuring gbm, hence
breaking up the dependency of configurations.

Define core multi-target regression tree structure. (#8884)
- Define a new tree struct embedded in the `RegTree`.
- Provide dispatching functions in `RegTree`.
- Fix some c++-17 warnings about the use of nodiscard (currently we disable the warning on
  the CI).
- Use uint32_t instead of size_t for `bst_target_t` as it has a defined size and can be used
  as part of dmlc parameter.
- Hide the `Segment` struct inside the categorical split matrix.

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.
