Eliminate usage of global transaction for display configuration.
For seamless rotation to work in the brave new world we need the setting
of the display projection to occur in the same transaction as the
reconfiguration of the stack SurfaceControl. To understand this simply see
that the inverse rotation for seamless rotation happens at the
WindowStateAnimator level so if the stack bounds weren't updated to the new
rotation we would clip. This means: We need to use the pending transaction.
We also need to port the rotation animation to use the pending transaction
as it needs to perform transactions at the same time as setting the display
projection. A pleasant consequence is we can eliminate some "inTransaction"
code-paths that always seemed to be a bit of a wart.
