Implement a skeleton of Mojo Application manifests.

In this first cut, when a local .mojo or .exe target is loaded, we look for a manifest json file nearby and consume it into a catalog maintained by the PackageManagerImpl.

Default manifests are provided for several interesting Mojo apps in Chromium, with pretty names to make the Mash Task Viewer look a little nicer.

Future CL improvements:
- comprehensive testing. currently mojo_shell_apptests is broken due to the EDK change.
- persisting the consumed catalog in a single store (e.g. Preferences) so that we don't need to read a bunch of files every startup. i.e. implement ApplicationCatalogStore.
- block creating the ApplicationInstance on having read the manifest, so the base CapabilityFilter is understood.
- implement base CapabilityFilter application.
