Use sync transaction for insets animation

Otherwise if the display is rotating with sync transaction,
the insets animation leash may apply the rotated position
too early.

Bug: 199836343
Test: setprop persist.debug.shell_transit 1; reboot
      Rotate display and check status/nav bar won't show
      in weird position before executing rotation animation.
