In place split install native support

This change makes it possible for apps installed with the DONT_KILL flag
set to obtain access to newly installed native libraries while avoiding
double load of existing native libraries prior to the install when
loaded using System.loadLibrary.

Bug: 72047376
Test: manual - used sample app to verify availability of native libs
