Refactor motion customization APIs according to UXR feedback

1. Removes the customization entry point from the scaffold functions.
2. Adds enterTransition, exitTransition, and boundsAnimationSpec
   directly to AnimatedPane so it will be clear that AnimatedPane can be
   customized via those parameters.
3. Hides ThreePaneMotion calculation functions as there seems no obvious
   usages of them.

Relnote: "Moves the entry point of pane motion customization from
  the scaffold functions to AnimatedPane according to UXR feedback."
