Exposing content insets and minimized home bounds for recents transition

- In order to calculate the final target rect and window clip for the
  app currently transitioning into the task view in launcher (similar to
  how we did in SysUI), we need to provide the content insets and bounds
  for both the app and launcher (whose activity may not yet have been
  shown).  For the existing recents transition, this was calculated
  internally in the AppTransition aspect-scaled transition, but now that
  we are implementing this via remote animations, the same information is
  needed in the implementation of the recents animation runner.
