Cloned estimators have identical randomness but different RNG instances

### Describe the bug

Cloned estimators have identical randomness but different RNG instances. According to documentation, it should be the other way around: different randomness but identical RNG instances.

Related #25395 

The User Guide [says](https://scikit-learn.org/stable/common_pitfalls.html#controlling-randomness):
> For an optimal robustness of cross-validation (CV) results, pass RandomState instances when creating estimators

> ```python
> rf_inst = RandomForestClassifier(random_state=np.random.RandomState(0))
> cross_val_score(rf_inst, X, y)
> ```
> ...
> Since `rf_inst` was passed a `RandomState` instance, each call to `fit` starts from a different RNG. As a result, the random subset of features will be different for each folds

In regards to cloning, the same reference says:
> ```python
> rng = np.random.RandomState(0)
> a = RandomForestClassifier(random_state=rng)
> b = clone(a)
> ```
> Moreover, `a` and `b` will influence each-other since they share the same internal RNG: calling `a.fit` will consume `b`’s RNG, and calling `b.fit` will consume `a`’s RNG, since they are the same. 

The actual behaviour does not follow this description. 

### Steps/Code to Reproduce

```python
import numpy as np
from sklearn import clone
from sklearn.datasets import make_classification
from sklearn.model_selection import cross_validate
from sklearn.ensemble import RandomForestClassifier

rng = np.random.RandomState(0)
X, y = make_classification(random_state=rng)
rf = RandomForestClassifier(random_state=rng)

d = cross_validate(rf, X, y, return_estimator=True, cv=2)
rngs = [e.random_state for e in d['estimator']]
# estimators corresponding to different CV runs have different but identical RNGs:
print(rngs[0] is rngs[1]) # False
print(all(rngs[0].randint(10, size=10) == rngs[1].randint(10, size=10))) # True

rf_clone = clone(rf)
rngs = [rf.random_state, rf_clone.random_state]
print(rngs[0] is rngs[1]) # False
print(all(rngs[0].randint(10, size=10) == rngs[1].randint(10, size=10))) # True
```

COMMENT:
My take on point 6 in https://github.com/scikit-learn/scikit-learn/issues/26148#issuecomment-1536979006 is that it should result in 2 different random forests, thus the assert should fail. Otherwise we make it hard for someone who knows what she is doing with rng.

Can't we make `GridSearchCV` aware that the (meta) estimator (eg. pipeline) supports a `random_state` argument? SLEP006 maybe?
If grid search knows that, it can clone and then set the random state of the cloned object.
