Remove OutputDevice::PaintScope

PaintScope was introduced in
    commit bfceb557efcd607ef018ae35fc73f8d61a9b9a4e

        GL paint-flushing guard re-work.

        Unfortunately, since we can have 2x SalGraphics' on a
OutputDevice,
        and one of these can be a printer - things got very confused
around
        which context to glFlush. This de-tangles the various reference-
counts.

and then mostly removed in
    commit 33fac4828038bc38ab4a0c4b891d762a5ae73e5e

        loplugin:unnecessaryvirtual

        and unwind some apparently now unused VCL OpenGL and
GlyphCachePeer
        stuff.

Finish the job, it's not doing anything at all anymore
