Found after running bin/find-unneeded-includes --headersfwd include/vcl/[A-Z]*
This shaves off about 100M input, not bad for such a small amount
of files checked
This time --headersfwd skips files that contain #if defs,
in hope of not breaking builds that are not checked by CI
(...except for include/vcl/BitmapTools.hxx - this was cleaned accidentally,
due to a bug in the bin/find-unneeded-includes script that is fixed
by the previous commit 930ff2b830
- but let's keep this anyway, it seems fine)
