Launch Panic gesture from SysUI

- Add StatusBar interface for launching panic gesture
- Add basic method to launch the panic gesture in sysui
- Swap call to launch telephony to launching eshare intent

Tested in Pixel 3a using the Settings Panel intent (since it resolves)
and found that it does indeed launch ontop of the camera (see
screenshot) and turns off the screen. These can be fixed in a later CL.
