Restore saveLayer APIs back into the public API.

The saveLayer APIs are restored from @removed but will treat input
as ALL_SAVE_FLAGS and generate exceptions on newer API levels.

We internally used these calls in one situation that now use a
different @hide API to support the previous behavior until we
refactor that code.
