Add suffix field to entities and use it to allow the counter ID to be changed

alexpott → credited daniel.bosen → .

Discussed this with @daniel.bosen we agreed that we should leverage the work in 📌 Add revision ID and VG Wort counter ID to vgwort_entity_registration Fixed to allow a new VG Wort ID to be generated.

The current idea is to add a new field which is a positive integer. This field will either be a base field added by the module to entity types configured to use VG Wort or a user created field and configured similar to how participant fields are handled. I think given [#2907785] that using base fields might be possible and probably desirable because we would not want the field to be revisionable or translatable.

If this field has a non empty value then it will be appended to the VG Wort ID in \Drupal\vgwort\Plugin\Field\CounterIdFieldItemList::computeValue().

There are still questions about how the suffix counter will be increased:

• Should we have a UI for this? If so how do we prevent abuse?
• Can we detect that a previously published entity is becoming published again and when this happens should we increase the counter? And if so, are there situation where we would not want this to happen.

LGTM
