Allow framework-connectivity to depend on framework-connectivity-t
stubs, and framework-connectivity-t to depend on prebuilt (to avoid
circular dependencies) framework-connectivity stubs to compile its own
stubs, and framework-connectivity.impl to compile its implementation.
Also reorganize jarjar rules so that service and framework jar can use
static libraries in framework-connectivity without packaging their own,
reducing duplicate code.
