Feature: #68746 - Add annotation for CLI only commands

See Issue #68746

Description

The PHPDoc annotation @cli was added to indicate Extbase CommandController commands to be usable on CLI only. In general each defined CommandController can be selected within the Extbase CommandController Task in the scheduler. For some commands like extbase:help:help running in a scheduler task is not wanted or needed. Now those commands can be excluded from the scheduler command selection.

Impact

Extbase CommandController commands annotated with @cli are not shown as command in the scheduler task.
