Handle swipe up after quick switch in overview grid

- If swipe up after task launches, move the task to be the first and focused it
- If swipe up before task launches, make sure the task can be sanpped to by moving ClearAllButton further away
- Before snapping to page on swipe up, make sure scroll calculation is up to date and consider the target gesture state
- Removed home task special casing in fallback recents, as the snapped page logic handles invariant scroll generically
- Invoke reset when launching home in fallback recents
