I would like to be able to fill_nulls per col/expr and on the dataframe level, akin to polars/pyspark/pandas

Describe the solution you'd like

Add a fill_null method to DataFrame struct, add fill_null logical expr.

This seems like it may almost be an alias for nvl or nvl2

@Omega359 indeed, for now I've opened a PR for a fill_null in datafusion-python that calls nvl: https://github.com/apache/datafusion-python/pull/919
