v112.1.0

This minor change introduces two new features and fixes crashes due to UIPointerInteraction use in
iOS 13 betas.

New features

BottomDrawer's MDCBottomDrawerPresentationControllerDelegate has a new method,
bottomDrawerDidTapScrim:. This method is invoked when the user taps the background behind the
bottom drawer.

MDCBaseTextFieldDelegate and its sole method, baseTextFieldDidDeleteBackward: have been added to
TextControls.
