Add navigation shortcuts to apps

[joelghill]

Summary

This PR adds swipe gestures to improve navigation:

1. Swiping to the right will dismiss the current screen and return the user to the home screen.
2. While on the home screen, and if an app has been previously opened, swiping to the left will return the user to the last used app.

Notes

1. Some apps rely on swiping gestures. In these cases the app has priority in processing gestures. Example is the music app for skipping forward or back.
2. The home screen shortcut doesn't work on the settings page since it's conceptually to the left of the home screen and it felt weird.

This implements an idea I pitched here: #2280

I made a mistake in documenting a swipe right gesture that will navigate back to the watch face. The logic is there, but it doesn't appear to work in the simulator.

Edit
The gestures as described work on my personal device, not sure why the simulator does not have the same behavior

Edit 2
It works in the simulator too, user error haha.
