[Ravenwood] Copy font and ICU data into ravenwood-runtime

We need to put font and data file references into filegroups with the
proper variant and reference it in android_ravenwood_libgroup { data } and android_ravenwood_libgroup { font }, or else soong will complain about mismatching variants when building if we directly reference these modules.
