Add updatable_media_stub to framework

The module framework is now a build-only library whose purpose is to
provide hidden APIs from the non-updatable part of the platform and APIs
from the modules. Merging updatable_media_stub to framework, like the
stub libraries from other modules.

As a result, updatable_media_stub can be removed from DefaultLibraries.
