[List] SelfSizingStereoCell with support for MDCCollectionViewCellAccessoryType / custom accessory view

[atebitsy]

Support for MDCCollectionViewCellAccessoryType would allow to use e.g. MDCCollectionViewCellAccessoryDisclosureIndicator to display a chevron on the trailing side of the cell to indicate that the action would cause a push.

Support for a custom accessory view would allow to add a UISwitch to the cell, in place of the MDCCollectionViewCellAccessoryType.
