Remove entity_print_commerce_order from Drupal 8 version

The commerce order sub-module doesn't work with D8 at this stage because Drupal Commerce wasn't ready when I ported the module to Drupal 8.

I think we should convert the entire module here if we want to make it work.

Postponing this for now until Commerce at least gets a beta/rc

Commerce 2.x already in beta5

And it seems the Entity Print is desired in Commerce core - as a solution for receipts/invoicing.
So, please check the related issue - #2831952: Create an entity_print renderer for orders (to allow order PDF output) - and the patch there.

I don't think that entity_print should ship with any Commerce-specific integration or templates, that should go in Commerce itself.

Yeah agreed with @bojanz, in D7 the sub-module was simply an example of how you would go about styling a specific entity and Commerce was the sample. I'll review the core Commerce issue asap.

I realised that the sub-module still exists from the D7 days although it's non-functional. Using this issue to go ahead and remove it from the codebase entirely.

Committed.
