        [Android] Android needs ResourceHandle implementation
        https://bugs.webkit.org/show_bug.cgi?id=32515

        Adds implementation of ResourceHandle on Android.

        No new tests needed, this is platform-specific code, so existing
        tests are sufficient.

        * platform/network/android/ResourceHandleAndroid.cpp: Added.
