Subject: [PATCH] docs: restore "Constants" page in Doxygen >=1.9.8

deltachat.h uses `@defgroup` commands to create topics
for groups of constants. Prior to Doxygen 1.9.8
defining a group created a "module"
and all constants were visible from the modules.html page.
In Doxygen 1.9.8 "modules" were renamed into "topics"
as C++20 modules have taken their place,
so Delta Chat documentation does not have modules
in Doxygen sense anymore.

The change is to replace "modules.html" with "topics.html"
in the DoxygenLayout.xml.

See <https://www.doxygen.nl/manual/grouping.html> for
Doxygen documentation about groups and their relation to topics.
