Provide alter for the field type UI definitions

I think we should create change record for this and update https://www.drupal.org/node/3364263 → to reference it.

Added a draft CR.

Discussed with @lauriii and we think that adding \Drupal\Core\Field\FieldTypePluginManagerInterface::getUiDefinitionsForEntityType($entity_type_id); is better than burying this alter in field_ui code.

Addressed #5 and tests are passing.

Renamed the alter hook based on feedback from @alexpott.

https://git.drupalcode.org/project/drupal/-/merge_requests/5802/diffs?co... proves we have good test coverage of comment's usage so that's nice!

I think adding this to the Field type manager is good because burying it in the field UI module would make it hard to discover and trickier for anything building field ui improvements in contrib.

Asked @lauriii for a 10.2.x version without any interface changes or deprecations for 10.2.x, and committed the respective patches to each branch, thanks!
