Imported from GitHub PR #18042

The open PR for issue #16202 looks to be dead, and having conflicts. So I have added some checks in DataHandler to catch empty input and steps. I did not edit the error message in fit like the last PR did, as it looks to have been updated already.

This PR improve error message to give more useful feedback:

• if passing empty dataset or array as input data
• if passing steps_per_epoch=0

to Model.fit() by adding checks in DataHandler.
