[BUGFIX] Avoid trimming of user login data with spaces at the end/beginning

Currently TYPO3 Core does trimming based on the user (AbstractUserAuthentication)
but in order to allow third-party extensions to integrate users / passwords
with spaces at the end and beginning, this code is moved to the Authentication
Service which allows for custom services to trim or not to trim individually.
