Use seamless for collecting transition with fixed rotation

When swiping up to enter PiP (auto-pip), the transition type will
PiP. If it affects display orientation at the same time, the
next activity will have fixed rotation transform. Then the display
should also use seamless rotation to avoid taking screenshot
and flickering of overlay windows (e.g. round corner) because the
draw transaction is not synced.

Also correct task transform for a corner case: expanding PiP to
different orientation, but display orientation is changed to
previous orientation during the animation. Then there is no next
transition to reset rotation transform of task. So manual reset
it when receiving a cancel event of the change.

Test: Enable shell transition.
      Use Chrome to play a Youtube video in fullscreen landscape.
      Enter PiP mode by swiping to home.
      The round corner and cutout should not be flickering.
