token: disallow multiple tokens with same name (#5820)

* api/v1: don't allow multiple tokens with same name

Fail with 422 Unprocessable Entity if the token name
already exist

ref: https://github.com/gogs/gogs/issues/5587

* Move new token error type to models/errors/token

* Remove "useless" ListAccessTokensByName function

* Add an i18n entry for token_name_exists
