Fixes #27843 (see also #27891 and #23734)

This PR adds a new feature to _SetOutputMixin that makes it possible for wrap inverse_transform method in sub classes and transform the output.

from sklearn.preprocessing import StandardScaler
from sklearn.datasets import load_breast_cancer

X, _ = load_breast_cancer(return_X_y=True, as_frame=True)

scaler = StandardScaler()

scaler.set_output(
	transform="pandas", inverse_transform="pandas"
)
scaler.fit(X)
Xt = scaler.transform(X)

print(scaler.inverse_transform(Xt))
