Expose angular as a dependency which can be included
from AMD-style modules, utilizing the extensions to
the framework layer added to support exposing libraries
from bundles. WTD-568.
Add an (empty) bundle definition for the framework
component. This has the practical effect of avoiding
404 errors in the console log, since platform/framework
is included in bundles.json (the set of active bundles)
in order to ensure detection by the test framework.
This also provides a place for possible future
extensions provided by the framework itself.
