[DO NOT MERGE] Support native shared libs - CTS

Add the shared libs that are APKs to the native library
path when creating application class loaders. Also don't
allow shared libraries hosting native libs to request
extraction of the native libs out of the APK. Lastly,
shared libraries hosting native libs must be declared
as multi-architecture.

Test: These are the tests :)
