Allow usage of "taxonomy_term_reference" field widget and formatter for base fields

Problem/Motivation

Follow-up from #2211553: Allow usage of entity_reference field widget and formatter for base fields.
TermAutocompleteController uses fieldInfo to get field definition so there's no ability to use autocomplete widget for base fields in custom entities

Proposed resolution

Use \Drupal\Core\Entity\EntityManager::getFieldDefinitions() to return field definition
