[TASK] Remove unused internal methods in BackendUtility

The internal methods
* BackendUtility::blindUserNames()
* BackendUtility::blindGroupNames()
* BackendUtility::getBackendScript()
are not in use anymore by TYPO3 Core and are removed.

Also fix Breaking-91473-DeprecatedFunctionalityRemoved.rst
to not reference BackendUtility::getBackendScript() as
breaking removal, as it was an internal method.

Resolves: #93001
