[MFill Android] Create view binder for modern accessory sheet

This CL adds and connects the new view binder which creates chips and
footer commands based on the AccessorySheetTab data.

In order to make the "ripple effect" work for chips, the drawable draws
a large rounded rectangle in the background color over the animated
image which effectively cuts and rounds the corners.
