This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.
Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.

* Apply the default Oreo theme and inherit the layouts
from Google for the Settings app, in order to keep
UI consistency.
* Get rid of SettingsDrawerActivity as it no longer fits in
and include the back button in the action bar.
* Kill the icon drawable not only because is a leftover,
but also doesn't really serve any puropose in the new UI.
