Support --limit option in entity:delete command

[tibezh]

Is your feature request related to a problem? Please describe.
I have similar that already described her #5784.

On the website with Drupal Commerce I have >5K commerce_order entities, I need to delete ALL of them, and got memory_limit error (with memory_limit=-1 in php.ini) for a command: drush entity:delete commerce_order

Describe the solution you'd like
I think we can have a little improvement for the entity:delete command and use a little trick to delete entities with bash loop.
I mean run command like:
i="0"; while [ $i -lt 100 ]; do $DRUSH entity:delete commerce_order --limit=500; i=$[$i+1]; done

Describe alternatives you've considered
I've tried to execute drupal_static_reset() function after each drush batch iteration and it not helped, still have memory leaks.

Additional context
Will provide a PR a little bit later.
