Add support for commerce conditions

Moving this to the new project which integrates ECA with Commerce.

Tagging for Drupal Dev Days next week.

Conditions where the config form features a commerce_entity_select form element (e.g.

Drupal\commerce_product\Plugin\Commerce\Condition\OrderProductType

, not sure if there's more) don't yet work with bpmn. Once this gets merged we need a followup issue for these.

This is great work, thanks a lot @czigor for this contribution.

I've reviewed the code and left some suggestions; only minor stuff. But I haven't tested it.

Thanks for the review, fixed everything.

Little new to the merge request workflow... I tried to squash the commits, but they keep getting separated. Is this going to be fixed on merge?

Nice, thanks. Only one minor comment left. I wonder if anyone could also test this in a commerce installation? I don't have one around right now, but that would be important before we merge this.

@czigor no worries about the commits. While working on an MR it's actually quite handy to have access to each individual commit to follow the taken steps. When the MR gets merged, then we can optionally sqaush them.

I'm planning on testing it today, thanks for the code review @jurgenhaas
