Vadim Zeitlin 3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword. 
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.

Notice that the 8 lower bits overlap with wxCENTRE and the button selection
bits (wxYES, wxOK wxNO, wxCANCEL, wxAPPLY, wxCLOSE and wxNO_DEFAULT) which
can be combined with the dialog style for several standard dialogs and
hence shouldn't overlap with any styles which can be used for the dialogs.
Additionally, wxCENTRE can be used with frames also.
