* feat(mouse): Add mouse move and scroll support
* Use Zephyr input subsystem for all pointers.
* Input processors for modifying events, e.g. scaling, swapping
codes, temporary (mouse) layers, etc.
* Mouse move/scroll behaviors.
* Infrastructure in place for physical pointer input devices.
* feat: Add input split support.
* docs: Add initial pointer docs.
