Huaxin Gao 901ff92969 [SPARK-29464][PYTHON][ML] PySpark ML should expose Params.clear() to unset a user supplied Param 
### What changes were proposed in this pull request?
change PySpark ml ```Params._clear``` to ```Params.clear```

### Why are the changes needed?
PySpark ML currently has a private _clear() method that will unset a param. This should be made public to match the Scala API and give users a way to unset a user supplied param.

### Does this PR introduce any user-facing change?
Yes. PySpark ml ```Params._clear``` ---> ```Params.clear```

### How was this patch tested?
Add test.

Closes #26130 from huaxingao/spark-29464.
