Refactor Wallet double tap power launch to be handled by SysUI instead of core.

Previously, GestureLauncherService in core was manually handling
launching the wallet app.

With this change, core notifies SysUI that wallet launch gesture was
detected, and SysUI handles the wallet launch. This follows the same
pattern that camera/emergency launch use with the power button shortcut.

This will allow SysUI to handle dismissing the keyguard before launching wallet.
