[TASK] Remove @internal for MfaProvider classes

The following classes were marked as @internal in TYPO3 11 since
the feature was experimental. This should have been removed with
TYPO3 12. The @internal has now been removed for:
\TYPO3\CMS\Core\Authentication\Mfa\MfaProviderInterface
\TYPO3\CMS\Core\Authentication\Mfa\MfaProviderPropertyManager
\TYPO3\CMS\Core\Authentication\Mfa\MfaViewType
