[!!!][TASK] Replace config.persistence.classes typoscript

This patch removes support for the configuration of
persistence related classes via typoscript. This is done
as typoscript is too variable, i.e. the configuration may
change depending on the day, the hour and whatever
possibility typoscript has when it comes to conditions.

The functionality must not vanish completely, but the
configuration should be immutable and predictable at an
early stage of the runtime.

To achieve this, the configuration has to be added to files
like EXT:Configuration/Extbase/Persistence/Classes.php

This patch is considered breaking as the configuration via
typoscript stops working immediately and the configuration
syntax slightly changed.

The easiest way to migrate to the new syntax is to have a
look at configuration files in core extensions.
