Subject: [PATCH] libinput: method to get `libinput_tablet_tool` from
 ITabletTool (#278)

* libinput: method to get `libinput_tablet_tool` from ITabletTool

Libinput has some configuration specific to the tablet tool that could
be interesting to set for Tablet users. However there's currently no
way of getting the required `libinput_tablet_tool` ptr from
`ITabletTool`. Meaning it's not possible to build the configuration on
Hyprland (or anything else using aquamarine).

This change adds the virtual function `getLibinputTool()` to
`ITabletTool` as well as an implementation for `CLibInputTabletTool`

* Run clang-format
