[input] Adds pointer fusion rust library

This change creates a rust library to fuse raw mouse and touch events
into PointerEvent. This is based off similar implementations found in
Flutter [1],[2] and Chromium [3]. The client of this library will be
AppKit [4] and it's clients.

- This first implementation only fuses mouse events, touch events will
  follow in subsequent cls.
