Allow multiple input device in the same window
With this change, all restrictions about only having a single input
device active in a window are lifted.
The window will get multiple input devices at once.
21 native tests were forked in this CL to reflect the new behaviour.
Bug: 211379801
Test: navigate settings with touch + stylus at the same time
Test: swipe inside IME with touch + stylus
Test: draw in test app with touch + stylus
