[Media TTT] Make the SwipeUpGestureHandler generic.

The media swipe gesture will re-use SwipeUpGestureHandler, so this CL
removes the status-bar-specific items from the handler.

Bug: 262584940
Test: verify swiping the status bar away when there's an ongoing call
still works
Test: Verify SwipeUpLog logs still appear
Test: atest OngoingCallControllerTest
