Matej Knopp e016cf4d04 [macOS] Handle interleaved movement and gesture events (flutter/engine#52201)
Fixes https://github.com/flutter/flutter/issues/146893

The crash happens, because with magic mouse, it is quite common to
receive `mouseExited:` event while the gesture event is still in
progress. This would reset the gesture state while the gesture event is
still active, leading to assertion when the gesture event ends.

The state machine assumes that when mouse exists that also ends any
gesture events. However that is not the case with magic mouse, which
handles the movement and gesture events separately.
