Samir Jindel 580f44aa83 [vm] Enable running FFI tests on Android in JIT-mode.
* Move FFI tests into a separate test suite.
  They never belonged in standalone_2/ since they are not only available in
  the standalone VM. Also, we want to have a separate status file.

* Add new "SharedObjects" option to test files to copy needed shared objects
  to the Android device for testing.

* Add support to compiler/runtime_configuration.dart for testing JIT-mode on Android.

* Add new configurations and builders to test_matrix.json to test JIT-mode on Android.

* Clean up status file entries for FFI (we didn't need to special-case stress & subtype tests).
