Add per SDK runtime loader support for Android and Default to LEGACY SQLite mode

1. As Robolectric is open sourced and the DefaultNativeRuntimeLoader is also used by third party.
It is concerned to add the per sdk runtime loading logic as default. Therefore adding such capibility as a part of the plug in for the Android platform only.
Made AndroidNativeRuntimeLoader a subclass of DefaultNativeRuntimeLoader to minimize sync problem from any future changes
2. Currently in AOSP native SQLite mode is not supported. Add a plugin to
default to legacy SQLite mode.
