[R] Fix global feature importance and predict with 1 sample. (#7394) 
* [R] Fix global feature importance.

* Add implementation for tree index.  The parameter is not documented in C API since we
should work on porting the model slicing to R instead of supporting more use of tree
index.

* Fix the difference between "gain" and "total_gain".

* debug.

* Fix prediction.

Change shebang used in CLI demo. (#7389) 
Change from system Python to environment python3.  For Ubuntu 20.04, only `python3` is
available and there's no `python`.  So at least `python3` is consistent with Python
virtual env, Ubuntu and anaconda.

Support multi-class with base margin. (#7381) 
This is already partially supported but never properly tested. So the only possible way to use it is calling `numpy.ndarray.flatten` with `base_margin` before passing it into XGBoost. This PR adds proper support
for most of the data types along with tests.

[jvm-packages] Fix json4s binary compatibility issue (#7376) 
Spark 3.2 depends on 3.7.0-M11 which has changed some implicited functions'
signatures. And it will result the xgboost4j built against spark 3.0/3.1
failed when saving the model.

Move skl eval_metric and early_stopping rounds to model params. (#6751) 
A new parameter `custom_metric` is added to `train` and `cv` to distinguish the behaviour from the old `feval`.  And `feval` is deprecated.  The new `custom_metric` receives transformed prediction when the built-in objective is used.  This enables XGBoost to use cost functions from other libraries like scikit-learn directly without going through the definition of the link function.

`eval_metric` and `early_stopping_rounds` in sklearn interface are moved from `fit` to `__init__` and is now saved as part of the scikit-learn model.  The old ones in `fit` function are now deprecated. The new `eval_metric` in `__init__` has the same new behaviour as `custom_metric`.

Added more detailed documents for the behaviour of custom objective and metric.
