Subject: Drop support for parsing/transforming content tags

The *content tags* are deprecated since July 2021 and have been replaced
by the more powerful *content functions*, but parsing/transforming the
old syntax was still supported until today.

This commit removes the logic to parse/transform the old *content tags*
from the codebase completely. If you are still using the old syntax in
your entities' content, you need to run a converter script.

Please look at the wiki for more information about *content functions*
and how to replace the old *content tags* with the converter script.
