shellDBus: Add ListExtensions() and GetExtensionInfo()

GetExtensionInfo() takes a UUID and returns a JSON object with information
about that extension including their metadata, path and current state.

ListExtensions() takes no arguments and returns a JSON object mapping UUIDs
to the same information objects described above.
