Removed outdated configuration serialization logic. (#8942) 
- `saved_params` is empty.
- `saved_configs_` contains `num_round`, which is not used anywhere inside xgboost.

Specify char type in JSON. (#8949) 
char is defined as signed on x86 but unsigned on arm64

- Use `std::int8_t` instead of char.
- Fix include when clang is pretending to be gcc.

Rework the MAP metric. (#8931) 
- The new implementation is more strict as only binary labels are accepted. The previous implementation converts values greater than 1 to 1.
- Deterministic GPU. (no atomic add).
- Fix top-k handling.
- Precise definition of MAP. (There are other variants on how to handle top-k).
- Refactor GPU ranking tests.

Refactor hist to prepare for multi-target builder. (#8928) 
- Extract the builder from the updater class. We need a new builder for multi-target.
- Extract `UpdateTree`, it can be reused for different builders. Eventually, other tree
  updaters can use it as well.

Reimplement the NDCG metric. (#8906) 
- Add support for non-exp gain.
- Cache the DMatrix object to avoid re-calculating the IDCG.
- Make GPU implementation deterministic. (no atomic add)

Remove public access to tree model param. (#8902) 
* Make tree model param a private member.
* Number of features and targets are immutable after construction.

This is to reduce the number of places where we can run configuration.

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.
