Only abort activity options when failing to bring a task to front

- If the activity options has a start callback, abort will prematurely
  call the callback prior to the app actually being good to go (and starting
  the app transition)
- Also exposing custom activity options call with callback to Launcher

Bug: 111896388
Test: Make change with launcher to defer hiding the task view until the
      transition-start callback, check that swiping down does not flicker
