[CCT][ToolbarRefactor] Implement chip animation

Implement CPA chip animation in the refactored flow. Unlike
pre-refactored code where the custom action button can be animated
along with the chip, the new code cannot do that. The difference is
that the former has the custom action/CPA as the children of
LinearLayout which lets the custom action move accordingly by giving
the Transition animation the right root view, while in the refactored
code they are independent (elements of FrameLayout), so the custom
action is not aware of the chip animation and stays where it is.

To resolve this, added a new callback API in OptionalButton MVC with
which the CustomTabToolbarButton MVC can specify the necessary
operation to make it animate accordingly.
