Update the name and the comment to explain better that this method returns the
state for which the bitmap is currently shown, not necessarily the current
state.
See #16771.
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.

Introduce wxAnyButton class, a common base class for wxButton and
wxToggleButton, allowing to reuse the same implementation for them.
This also allows to implement support for bitmaps in wxToggleButton for all
platforms and make wxBitmapToggleButton a trivial subclass of it everywhere,
similarly to wxBitmapButton and wxButton.
