For now the KoCreatePathTool has been moved there, but in the future we may move many more things
there.

Krita is adapted to use the new library instead of flake. Krita was the only one to use the class
directly.

The library also installs a plugin so the tool is available to users as before

Final change is that the CreatePath tool no longer has a snapping option widget (we already have
a new docker which holds the snapping options)
