Implemented DialerFloatingActionButton

Implemented wrapper class for FloatingActionButton to resolve some of
FloatingActinButton's many issues. One of which is alllowing clicks while
animating that was causing a crash in NUI.

This change also fixes an issue with the dialpad exit animation.

Bug: 73995512

+/**
+ * Since {@link FloatingActionButton} is possibly the worst widget supported by the framework, we
+ * need this class to work around several of it's bugs.
+ *
+ * <p>Current fixes:
+ *
+ * <ul>
+ *   <li>Being able to trigger click events twice.
+ *   <li>Banning setVisibility since 9 times out of 10, it just causes bad state.
+ * </ul>
+ *
+ * Planned fixes:
+ *
+ * <ul>
+ *   <li>Animating on first show/hide
+ *   <li>Being able to call show/hide rapidly and being in the proper state
+ *   <li>Having a proper 48x48 touch target in mini mode
+ * </ul>
