Description

https://github.com/alteryx/evalml/pull/2692 introduced a generic DropRowsTransformer but based on the thread here, it'd be a good idea to introduce a data-agnostic component which detects and drops nan rows.

This could probably be done by subclassing DropRowsTransformer and adding nan detection logic!
