Change screen pinning back to old gesture

Browse Source 
This makes the code a bit more complicated, but allows apps to
receive long-press back again and also makes the mode harder
to exit for toddlers.

Test: Without TalkBack enabled, make sure the following works:
- Enter multi-window mode with long pressing recents
- Long press back gets sent to the app.
- Enter screen pinning, make sure you can exit with gesture
