Support for MineMenuFabric

[leon0399]

It would be great to add support to bind actions and tweaks not only through keyboard shortcuts, but also throug MineMenu, cause I think I'll break my fingers at some point.

It doesn't look like MineMenu has any API or any easy way to interface with the custom keybind system from malilib.

However malilib itself will get a similar capability of creating custom "action screens" with buttons/widgets to trigger actions. That will be usable for any actions from any mods that use malilib.
