[TASK] Decouple usage of cObject->editPanel and ->editIcons

Both methods within "ContentObjectRenderer->editPanel()" and
"ContentObjectRenderer->editIcons()" were built to have "FrontendEditingController"
resolve the editing panel (EXT:feedit) which is not needed, so ContentObjectRenderer
is calling the extensions itself.

For that use, the FrontendBackendUserAuthentication gains functionality
for checking if a record can be edited.

Resolves: #85972
