Breaking: #92132 - Last remains of globals SOBE removed

See forge#92132

Description

The $GLOBALS['SOBE'] object has been used as a controller to sub module communication. It's usage has been reduced in previous core versions already. It is now fully removed.

Impact

Backend extensions that rely on $GLOBALS['SOBE'] may behave differently.

Affected Installations

Some old backend extensions may still rely on $GLOBALS['SOBE'] being set. The extension scanner will find usages.

Migration

Do not rely on $GLOBALS['SOBE'] being set anymore, hand over arguments to other classes directly.
