Due to a bug in MSVC handling of __VA_ARGS__ (see
https://connect.microsoft.com/VisualStudio/feedback/details/380090/variadic-macro-replacement)
wxCALL_FOR_EACH() didn't work correctly as long as more than two arguments
were used with it.
Work around the bug by protecting __VA_ARGS__ from being incorrectly passed as
a single token to the macro being called on every step: this was already done
for wxCALL_FOR_EACH itself with wxCALL_FOR_EACH_, but we need to do it for all
the helper macros too.
Also add a test checking that this does, actually, work.

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.
