Start recents animation to the target task in the stack

- If someone downloads a 3p launcher, there can be multiple tasks in the
  same target stack. When bringing the stack forward for quickstep, also
  bring forward the target task within the stack.

Bug: 77217592
Test: Install 3p launcher, go home (to that launcher), launch an app and
      then swipe up. We expect the default launcher with the overview
      implementation to show instead of the 3p launcher task above it.
