[!!!][TASK] Remove support for deprecated CLI command configuration

Configuration via Commands.php had been superseded by tag based
DI service configuration which allowed to configure DI and dependencies
for CLI commands in one place.

The CommandRegistry is refactored as the runtime merging logic
can now be dropped and handled in addLazyCommand – which is called
by the symfony DI generated factory – instead.
