Drawer updates for Media app

- Merging list and empty adapter functionality into CarDrawerAdapter.
  The adapter will display disabled-list item if flag set and no items
  are available to display.
- CarDrawerAdapter now supports cleanup when popped. Subclasses can perform
  any required cleanup.
- CarDrawerAdapter sets title from resource-string or bare-string.
  Media-app needs latter while Dialer/Radio use former.
- CarDrawerActivity supports setting main content view. MediaApp will
  use this (in upcoming CL).
