tdf#146551: improve native checkmark and bullet drawing on Windows

This takes marks' borders into account, and removes some hacks used
previously in place of those.

It introduces one new hack - adjusting only rectangle's top in
ImplPaintCheckBackground - to workaround one pixel less height of
selected images background on Windows, caused by the current method
of drawing that background, abusing toolbar button for that on all
platforms. Ideally, drawing it (or the whole image) should be
implemented using OutputDevice::DrawNativeControl with dedicated
ControlPart value, which would enable use of ImplDrawTheme with
MCB_BITMAP menu background state on Windows.

I have tested on Windows 10 (using both default and Skia drawing,
with normal and scaled UI), and on Ubuntu with gtk3, x11, and kf5
plugins (since common code is affected); it seems to give expected
results on all of them.
