> Add a HasIntermediateStorageLevel trait to sharedParams.scala, following the same pattern
> as other Has* param traits. Apply it to the following estimators that currently hardcode
> StorageLevel.MEMORY_AND_DISK for intermediate dataset persistence:
> Classification: LogisticRegression, LinearSVC, FMClassifier, OneVsRest
> Clustering: KMeans, GaussianMixture, LDA
> Regression: LinearRegression, AFTSurvivalRegression, FMRegressor, IsotonicRegression
> Other: FPGrowth
> Also update the corresponding PySpark classes.
> Part of SPARK-47103.
