Fix wrong use of Doxygen grouping-related markup which somehow worked in
older Doxygen versions, but doesn't work any longer.
This fixes the problem with the "Functions by Category" pages being
empty in the resulting HTML documentation and wrong documentation being
shown for a bunch of wxString members.
This is a combined cherry-pick of the following master commits:
bd92523bc5 Fix use of Doxygen @addtogroup command
4c46e01b14 Remove stray Doxygen end group marker
8ac10d28f8 Fix all the other comments with Doxygen grouping commands too
c0f1ecf263 Fix another unbalanced Doxygen grouping command after last commit
See #22248, #22572.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Use "wxWindows licence" and not "wxWidgets licence" (the latter doesn't
exist) and consistently spell "licence" using British spelling.
