[TASK] Restore newRecord level button behaviour

Since #82489 the "enabledControls['new']" option
did not longer hide the "New record" button of inline
containers as this was considered a misuse and led
to some misbehaviour. This option should only affect
the action buttons of each inline record.

However since this can be considered a breaking change,
especially because there is currently no option available
to only hide the "New record" button, the whole change
is reverted now and will only be fixed in a separate patch
for v11. This will be done by introducing a dedicated option
for the "new record" button and by deprecating the "none"
value of the "levelLinksPosition" option.
