Coding standards Issue fixes

Reviewed and found under sub-module gdpr_tasks/ gdpr_task.module still having phpcs issue

 14 | WARNING | [x] Unused use statement
 68 | ERROR   | [ ] All functions defined in a module file must be prefixed with the module's name, found "gdpr_fields_entity_type_alter" but expected "gdpr_tasks_gdpr_fields_entity_type_alter"

Reviewed and it didn't get any warning or notice in phpcs command, hence moving into RTBC

Thank you for working, merged, release to follow shortly!
