binder: Add Java bindings for setInheritRt

This change adds Java functions for two features:

1. A wrapper for setInheritRt, which is available in libbinder but was
   previously not exposed to Java code.
2. A wrapper for setGlobalInheritRt to enable setInheritRt across all
   Binder instances within a process.

Flag: android.server.allow_system_server_inherit_rt
