Don't use impl lib of android.test.[mock|base|runners]

The java_sdk_library modules are now added with 'default_to_stubs: true'
so that their impl libraries are not used even when the clients don't
have sdk_version property set.

This will allow us to replace the direct references to the stub
libraries of the java_sdk_library modules with the references to the
modules themselves (e.g. android.test.base.stubs -> android.test.base)
in many of the CTS tests without unintentionally exposing the private
APIs in the impl lib.

As part of the change, MockContentProvider.getIContentProviderBinder()
now returns an anonymous Binder object instead of throwing an exception.
This is to eliminate the need for clients to override the now
inaccessible method to escape from the exception.

Also, InstrumentationTestRunner.addTestListener method is added to the
stub because it is used by several tests (MtpServiceTests, etc.)
