Gil Forsyth 92ae3abc97 [dask] Disallow importing non-dask estimators from xgboost.dask (#7133) 
* Disallow importing non-dask estimators from xgboost.dask

This is mostly a style change, but also avoids a user error (that I have
committed on a few occasions).  Since `XGBRegressor` and `XGBClassifier`
are imported as parent classes for the `dask` estimators, without
defining an `__all__`, autocomplete (or muscle) memory will produce the
following with little prompting:

```
from xgboost.dask import XGBClassifier
```

There's nothing inherently wrong with that, but given that
`XGBClassifier` is not `dask` enabled, it can lead to confusing behavior
until you figure out you should've typed

```
from xgboost.dask import DaskXGBClassifier
```

Another option is to alias import the existing non-dask estimators.

* Remove base/iter class, add train predict funcs

Jiaming Yuan 5d7cdf2e36 [Breaking] Rename Quantile DMatrix C API. (#7082) 
The role of ProxyDMatrix is going beyond what it was designed.  Now it's used by both
QuantileDeviceDMatrix and inplace prediction.  After the refactoring of sparse DMatrix it
will also be used for external memory.  Renaming the C API to extract it from
QuantileDeviceDMatrix.

Jiaming Yuan 615ab2b03e Extract evaluate splits from CPU hist. (#7079) 
Other than modularizing the split evaluation function, this PR also removes some more functions including `InitNewNodes` and `BuildNodeStats` among some other unused variables.  Also, scattered code like setting leaf weights is grouped into the split evaluator and `NodeEntry` is simplified and made private.  Another subtle difference with the original implementation is that the modified code doesn't call `tree[nidx].Parent()` to traversal upward.
