Configure cub version automatically. (#7579) 
Note that when cub inside CUDA is being used, XGBoost performs checks on input size
instead of using internal cub function to accept inputs larger than maximum integer.

Rewrite approx (#7214) 
This PR rewrites the approx tree method to use codebase from hist for better performance and code sharing.

The rewrite has many benefits:
- Support for both `max_leaves` and `max_depth`.
- Support for `grow_policy`.
- Support for mono constraint.
- Support for feature weights.
- Support for easier bin configuration (`max_bin`).
- Support for categorical data.
- Faster performance for most of the datasets. (many times faster)
- Support for prediction cache.
- Significantly better performance for external memory.
- Unites the code base between approx and hist.
