Kan-Ru Chen 1e8d2f14b9 Bug 1194751 - Part 6.1 change nsScreenManagerAndroid::ScreenForId to a concrete method. r=snorp
nsIScreen::GetId and nsIScreenManager::ScreenForId is removed in patch
part 6. These methods are still used by Fennec on Android to implement
Presentation API support so I changed them to concrete methods in
nsScreenAndroid and nsScreenManagerAndroid.

nsScreenAndroid and nsScreenManagerAndroid does not use the generic
Screen and ScreenManager class because its implementation is quite
different.
