remove OpenGL VCL backend code

It is by now practically unmaintained, even bugreports in bugzilla
have been already closed for it. AFAICT this used to be really
used only on Windows, where it's no longer the default.

There's still some OpenGL code left, because there are still two
other places that use OpenGL. One is OpenGL slideshows, which
reuse some of the base OpenGL code (and I've checked they
still work even after this removal). Second one is OpenGL canvas,
which it seems has never been finished or enabled (or so it
most probably should be dumped too).
