graphviz: separate x11 binaries and gtk plugin to reduce deps
https://github.com/void-linux/void-packages/pull/32939

Description:
See #32826.

Arguably, the split of x11 is less important. It saves from `libXaw`, `libXmu` and `libXt`, but `libX11` and `libXrender` are deps via `cairo` anyway.

The split of `gtk` saves a lot of deps which are not usually installed on a server or chroot.

It is possible to make a smaller pkg without `gd`, `rsvg` and `webp` which seems good enough (renders svg and ps via core plugin, images and pdf via cairo), but probably not worth it.

Can't remove `pango` without disabling `cairo` as well; in this case one would want to keep `gd` for images. I wouldn't do this since the gd plugin is deprecated.
