Cancel gestures on launcher destroy

A wide variety of gesture navigation bugs were caused if launcher happened to be recreated mid-gesture and we didn't handle it gracefully. Updated lifecycle callbacks to immediately cancel the ongoing gesture if launcher is destroyed.

Fixes: 244593270
Fixes: 257976590
Test: forcefully(programmatically) recreate on every other gesture nav handle touch down; check that following gestures are not broken and animations are not frozen
